Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624632, here are decompositions:
- 5 + 31624627 = 31624632
- 19 + 31624613 = 31624632
- 41 + 31624591 = 31624632
- 73 + 31624559 = 31624632
- 269 + 31624363 = 31624632
- 283 + 31624349 = 31624632
- 293 + 31624339 = 31624632
- 311 + 31624321 = 31624632
Showing the first eight; more decompositions exist.
