Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31632, here are decompositions:
- 5 + 31627 = 31632
- 31 + 31601 = 31632
- 59 + 31573 = 31632
- 89 + 31543 = 31632
- 101 + 31531 = 31632
- 151 + 31481 = 31632
- 163 + 31469 = 31632
- 239 + 31393 = 31632
Showing the first eight; more decompositions exist.
