Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607928, here are decompositions:
- 7 + 31607921 = 31607928
- 19 + 31607909 = 31607928
- 31 + 31607897 = 31607928
- 59 + 31607869 = 31607928
- 61 + 31607867 = 31607928
- 71 + 31607857 = 31607928
- 89 + 31607839 = 31607928
- 97 + 31607831 = 31607928
Showing the first eight; more decompositions exist.
