Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609116, here are decompositions:
- 5 + 31609111 = 31609116
- 23 + 31609093 = 31609116
- 29 + 31609087 = 31609116
- 37 + 31609079 = 31609116
- 67 + 31609049 = 31609116
- 83 + 31609033 = 31609116
- 157 + 31608959 = 31609116
- 163 + 31608953 = 31609116
Showing the first eight; more decompositions exist.
