Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612504, here are decompositions:
- 17 + 31612487 = 31612504
- 23 + 31612481 = 31612504
- 113 + 31612391 = 31612504
- 191 + 31612313 = 31612504
- 197 + 31612307 = 31612504
- 227 + 31612277 = 31612504
- 263 + 31612241 = 31612504
- 281 + 31612223 = 31612504
Showing the first eight; more decompositions exist.
