Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624288, here are decompositions:
- 5 + 31624283 = 31624288
- 11 + 31624277 = 31624288
- 71 + 31624217 = 31624288
- 317 + 31623971 = 31624288
- 359 + 31623929 = 31624288
- 401 + 31623887 = 31624288
- 431 + 31623857 = 31624288
- 467 + 31623821 = 31624288
Showing the first eight; more decompositions exist.
