Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609760, here are decompositions:
- 19 + 31609741 = 31609760
- 37 + 31609723 = 31609760
- 67 + 31609693 = 31609760
- 151 + 31609609 = 31609760
- 199 + 31609561 = 31609760
- 211 + 31609549 = 31609760
- 229 + 31609531 = 31609760
- 241 + 31609519 = 31609760
Showing the first eight; more decompositions exist.
