Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133812, here are decompositions:
- 11 + 133801 = 133812
- 31 + 133781 = 133812
- 43 + 133769 = 133812
- 79 + 133733 = 133812
- 89 + 133723 = 133812
- 101 + 133711 = 133812
- 103 + 133709 = 133812
- 139 + 133673 = 133812
Showing the first eight; more decompositions exist.
