Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613276, here are decompositions:
- 139 + 31613137 = 31613276
- 157 + 31613119 = 31613276
- 223 + 31613053 = 31613276
- 307 + 31612969 = 31613276
- 337 + 31612939 = 31613276
- 523 + 31612753 = 31613276
- 547 + 31612729 = 31613276
- 613 + 31612663 = 31613276
Showing the first eight; more decompositions exist.
