Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539250, here are decompositions:
- 59 + 31539191 = 31539250
- 107 + 31539143 = 31539250
- 167 + 31539083 = 31539250
- 263 + 31538987 = 31539250
- 443 + 31538807 = 31539250
- 461 + 31538789 = 31539250
- 521 + 31538729 = 31539250
- 557 + 31538693 = 31539250
Showing the first eight; more decompositions exist.
