Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156670, here are decompositions:
- 11 + 156659 = 156670
- 29 + 156641 = 156670
- 47 + 156623 = 156670
- 131 + 156539 = 156670
- 149 + 156521 = 156670
- 179 + 156491 = 156670
- 233 + 156437 = 156670
- 251 + 156419 = 156670
Showing the first eight; more decompositions exist.
