Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612874, here are decompositions:
- 43 + 31612831 = 31612874
- 127 + 31612747 = 31612874
- 211 + 31612663 = 31612874
- 277 + 31612597 = 31612874
- 421 + 31612453 = 31612874
- 523 + 31612351 = 31612874
- 673 + 31612201 = 31612874
- 877 + 31611997 = 31612874
Showing the first eight; more decompositions exist.
