Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497626, here are decompositions:
- 67 + 31497559 = 31497626
- 79 + 31497547 = 31497626
- 103 + 31497523 = 31497626
- 157 + 31497469 = 31497626
- 163 + 31497463 = 31497626
- 313 + 31497313 = 31497626
- 397 + 31497229 = 31497626
- 439 + 31497187 = 31497626
Showing the first eight; more decompositions exist.
