Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463728, here are decompositions:
- 11 + 31463717 = 31463728
- 47 + 31463681 = 31463728
- 137 + 31463591 = 31463728
- 239 + 31463489 = 31463728
- 251 + 31463477 = 31463728
- 269 + 31463459 = 31463728
- 467 + 31463261 = 31463728
- 479 + 31463249 = 31463728
Showing the first eight; more decompositions exist.
