Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609756, here are decompositions:
- 53 + 31609703 = 31609756
- 173 + 31609583 = 31609756
- 179 + 31609577 = 31609756
- 257 + 31609499 = 31609756
- 263 + 31609493 = 31609756
- 293 + 31609463 = 31609756
- 467 + 31609289 = 31609756
- 677 + 31609079 = 31609756
Showing the first eight; more decompositions exist.
