Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463520, here are decompositions:
- 13 + 31463507 = 31463520
- 31 + 31463489 = 31463520
- 37 + 31463483 = 31463520
- 43 + 31463477 = 31463520
- 61 + 31463459 = 31463520
- 113 + 31463407 = 31463520
- 131 + 31463389 = 31463520
- 157 + 31463363 = 31463520
Showing the first eight; more decompositions exist.
