Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609536, here are decompositions:
- 5 + 31609531 = 31609536
- 17 + 31609519 = 31609536
- 37 + 31609499 = 31609536
- 43 + 31609493 = 31609536
- 67 + 31609469 = 31609536
- 73 + 31609463 = 31609536
- 83 + 31609453 = 31609536
- 197 + 31609339 = 31609536
Showing the first eight; more decompositions exist.
