Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156750, here are decompositions:
- 17 + 156733 = 156750
- 23 + 156727 = 156750
- 31 + 156719 = 156750
- 43 + 156707 = 156750
- 47 + 156703 = 156750
- 59 + 156691 = 156750
- 67 + 156683 = 156750
- 71 + 156679 = 156750
Showing the first eight; more decompositions exist.
