Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608084, here are decompositions:
- 17 + 31608067 = 31608084
- 23 + 31608061 = 31608084
- 37 + 31608047 = 31608084
- 43 + 31608041 = 31608084
- 47 + 31608037 = 31608084
- 71 + 31608013 = 31608084
- 113 + 31607971 = 31608084
- 163 + 31607921 = 31608084
Showing the first eight; more decompositions exist.
