Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609184, here are decompositions:
- 67 + 31609117 = 31609184
- 73 + 31609111 = 31609184
- 97 + 31609087 = 31609184
- 151 + 31609033 = 31609184
- 331 + 31608853 = 31609184
- 367 + 31608817 = 31609184
- 457 + 31608727 = 31609184
- 463 + 31608721 = 31609184
Showing the first eight; more decompositions exist.
