Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156626, here are decompositions:
- 3 + 156623 = 156626
- 7 + 156619 = 156626
- 37 + 156589 = 156626
- 139 + 156487 = 156626
- 307 + 156319 = 156626
- 367 + 156259 = 156626
- 373 + 156253 = 156626
- 397 + 156229 = 156626
Showing the first eight; more decompositions exist.
