Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539204, here are decompositions:
- 13 + 31539191 = 31539204
- 41 + 31539163 = 31539204
- 61 + 31539143 = 31539204
- 131 + 31539073 = 31539204
- 157 + 31539047 = 31539204
- 197 + 31539007 = 31539204
- 317 + 31538887 = 31539204
- 397 + 31538807 = 31539204
Showing the first eight; more decompositions exist.
