Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589962, here are decompositions:
- 71 + 31589891 = 31589962
- 101 + 31589861 = 31589962
- 191 + 31589771 = 31589962
- 251 + 31589711 = 31589962
- 269 + 31589693 = 31589962
- 401 + 31589561 = 31589962
- 449 + 31589513 = 31589962
- 479 + 31589483 = 31589962
Showing the first eight; more decompositions exist.
