Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596430, here are decompositions:
- 11 + 31596419 = 31596430
- 17 + 31596413 = 31596430
- 29 + 31596401 = 31596430
- 113 + 31596317 = 31596430
- 137 + 31596293 = 31596430
- 311 + 31596119 = 31596430
- 389 + 31596041 = 31596430
- 401 + 31596029 = 31596430
Showing the first eight; more decompositions exist.
