Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528176, here are decompositions:
- 5 + 31528171 = 31528176
- 7 + 31528169 = 31528176
- 19 + 31528157 = 31528176
- 73 + 31528103 = 31528176
- 83 + 31528093 = 31528176
- 107 + 31528069 = 31528176
- 109 + 31528067 = 31528176
- 139 + 31528037 = 31528176
Showing the first eight; more decompositions exist.
