Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617746, here are decompositions:
- 67 + 31617679 = 31617746
- 73 + 31617673 = 31617746
- 79 + 31617667 = 31617746
- 163 + 31617583 = 31617746
- 337 + 31617409 = 31617746
- 367 + 31617379 = 31617746
- 373 + 31617373 = 31617746
- 463 + 31617283 = 31617746
Showing the first eight; more decompositions exist.
