Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618864, here are decompositions:
- 41 + 31618823 = 31618864
- 83 + 31618781 = 31618864
- 113 + 31618751 = 31618864
- 227 + 31618637 = 31618864
- 317 + 31618547 = 31618864
- 401 + 31618463 = 31618864
- 461 + 31618403 = 31618864
- 503 + 31618361 = 31618864
Showing the first eight; more decompositions exist.
