Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539222, here are decompositions:
- 31 + 31539191 = 31539222
- 59 + 31539163 = 31539222
- 79 + 31539143 = 31539222
- 139 + 31539083 = 31539222
- 149 + 31539073 = 31539222
- 179 + 31539043 = 31539222
- 271 + 31538951 = 31539222
- 433 + 31538789 = 31539222
Showing the first eight; more decompositions exist.
