Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542464, here are decompositions:
- 7 + 31542457 = 31542464
- 67 + 31542397 = 31542464
- 73 + 31542391 = 31542464
- 397 + 31542067 = 31542464
- 433 + 31542031 = 31542464
- 463 + 31542001 = 31542464
- 487 + 31541977 = 31542464
- 571 + 31541893 = 31542464
Showing the first eight; more decompositions exist.
