Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609426, here are decompositions:
- 137 + 31609289 = 31609426
- 197 + 31609229 = 31609426
- 347 + 31609079 = 31609426
- 467 + 31608959 = 31609426
- 509 + 31608917 = 31609426
- 647 + 31608779 = 31609426
- 677 + 31608749 = 31609426
- 839 + 31608587 = 31609426
Showing the first eight; more decompositions exist.
