Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497632, here are decompositions:
- 31 + 31497601 = 31497632
- 73 + 31497559 = 31497632
- 109 + 31497523 = 31497632
- 163 + 31497469 = 31497632
- 223 + 31497409 = 31497632
- 241 + 31497391 = 31497632
- 349 + 31497283 = 31497632
- 409 + 31497223 = 31497632
Showing the first eight; more decompositions exist.
