Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489502, here are decompositions:
- 13 + 31489489 = 31489502
- 103 + 31489399 = 31489502
- 139 + 31489363 = 31489502
- 223 + 31489279 = 31489502
- 433 + 31489069 = 31489502
- 439 + 31489063 = 31489502
- 523 + 31488979 = 31489502
- 571 + 31488931 = 31489502
Showing the first eight; more decompositions exist.
