In 1741 Christian Goldbach conjectured that every even number could be written as a sum of two primes. [At the time 1 was considered a prime and so 2 = 1 + 1.] The conjecture has not been proven so there may be even numbers which cannot be so written. Also every number which is greater than 5 and is one fewer than a multiple of 6 cannot be so written.
Numbers 10 and less can be written numerically, e.g. 5 is written as 5. Numbers greater than 10 should be spelled out so 49 should be written as forty-nine.
No.
5 hundredths is greater. Whether the numbers are written as decimals or fractions, or in some other base is totally irrelevant.

it is known as gold bach conjecture since 1742
No. 2 is even and cannot be written as a sum of 2 prime numbers.For even numbers greater than 2, this is the Goldbach conjecture, one of the best known conjectures. It has been shown to hold true up to 4*10^18 but has not been proved.

It can't be one. Mixed numbers are greater than one.

Those are composite numbers.
