Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617824, here are decompositions:
- 13 + 31617811 = 31617824
- 61 + 31617763 = 31617824
- 67 + 31617757 = 31617824
- 127 + 31617697 = 31617824
- 151 + 31617673 = 31617824
- 157 + 31617667 = 31617824
- 193 + 31617631 = 31617824
- 241 + 31617583 = 31617824
Showing the first eight; more decompositions exist.
