Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609704, here are decompositions:
- 11 + 31609693 = 31609704
- 13 + 31609691 = 31609704
- 43 + 31609661 = 31609704
- 73 + 31609631 = 31609704
- 127 + 31609577 = 31609704
- 157 + 31609547 = 31609704
- 163 + 31609541 = 31609704
- 173 + 31609531 = 31609704
Showing the first eight; more decompositions exist.
