Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491632, here are decompositions:
- 13 + 31491619 = 31491632
- 19 + 31491613 = 31491632
- 43 + 31491589 = 31491632
- 61 + 31491571 = 31491632
- 163 + 31491469 = 31491632
- 349 + 31491283 = 31491632
- 379 + 31491253 = 31491632
- 433 + 31491199 = 31491632
Showing the first eight; more decompositions exist.
