Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156748, here are decompositions:
- 29 + 156719 = 156748
- 41 + 156707 = 156748
- 71 + 156677 = 156748
- 89 + 156659 = 156748
- 107 + 156641 = 156748
- 227 + 156521 = 156748
- 257 + 156491 = 156748
- 281 + 156467 = 156748
Showing the first eight; more decompositions exist.
