Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539174, here are decompositions:
- 11 + 31539163 = 31539174
- 31 + 31539143 = 31539174
- 101 + 31539073 = 31539174
- 113 + 31539061 = 31539174
- 127 + 31539047 = 31539174
- 131 + 31539043 = 31539174
- 167 + 31539007 = 31539174
- 223 + 31538951 = 31539174
Showing the first eight; more decompositions exist.
