Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530716, here are decompositions:
- 3 + 31530713 = 31530716
- 13 + 31530703 = 31530716
- 37 + 31530679 = 31530716
- 67 + 31530649 = 31530716
- 73 + 31530643 = 31530716
- 79 + 31530637 = 31530716
- 109 + 31530607 = 31530716
- 127 + 31530589 = 31530716
Showing the first eight; more decompositions exist.
