Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497028, here are decompositions:
- 71 + 31496957 = 31497028
- 107 + 31496921 = 31497028
- 359 + 31496669 = 31497028
- 461 + 31496567 = 31497028
- 491 + 31496537 = 31497028
- 509 + 31496519 = 31497028
- 587 + 31496441 = 31497028
- 599 + 31496429 = 31497028
Showing the first eight; more decompositions exist.
