Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513502, here are decompositions:
- 79 + 31513423 = 31513502
- 193 + 31513309 = 31513502
- 199 + 31513303 = 31513502
- 283 + 31513219 = 31513502
- 379 + 31513123 = 31513502
- 439 + 31513063 = 31513502
- 499 + 31513003 = 31513502
- 661 + 31512841 = 31513502
Showing the first eight; more decompositions exist.
