Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609088, here are decompositions:
- 151 + 31608937 = 31609088
- 271 + 31608817 = 31609088
- 331 + 31608757 = 31609088
- 367 + 31608721 = 31609088
- 421 + 31608667 = 31609088
- 499 + 31608589 = 31609088
- 607 + 31608481 = 31609088
- 661 + 31608427 = 31609088
Showing the first eight; more decompositions exist.
