Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540088, here are decompositions:
- 79 + 31540009 = 31540088
- 157 + 31539931 = 31540088
- 199 + 31539889 = 31540088
- 271 + 31539817 = 31540088
- 331 + 31539757 = 31540088
- 439 + 31539649 = 31540088
- 739 + 31539349 = 31540088
- 751 + 31539337 = 31540088
Showing the first eight; more decompositions exist.
