Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156700, here are decompositions:
- 17 + 156683 = 156700
- 23 + 156677 = 156700
- 29 + 156671 = 156700
- 41 + 156659 = 156700
- 59 + 156641 = 156700
- 107 + 156593 = 156700
- 179 + 156521 = 156700
- 233 + 156467 = 156700
Showing the first eight; more decompositions exist.
