Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612516, here are decompositions:
- 3 + 31612513 = 31612516
- 29 + 31612487 = 31612516
- 239 + 31612277 = 31612516
- 293 + 31612223 = 31612516
- 317 + 31612199 = 31612516
- 503 + 31612013 = 31612516
- 599 + 31611917 = 31612516
- 647 + 31611869 = 31612516
Showing the first eight; more decompositions exist.
