61 and 2
two prime numbers when added together will equal 63: 2 + 61
30 and 63 are relatively prime numbers. The factors of 30 are 1, 2, 3, 5, and 30, and the factors of 63 are 1, 7, 9, and 63. Two or more numbers are relatively prime if 1 is their only common factor.
3*3*7=63
The only way two prime numbers can add up to an odd number is if one of them is 2. Since 63 isn't prime, this pair doesn't exist.
