Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539848, here are decompositions:
- 31 + 31539817 = 31539848
- 199 + 31539649 = 31539848
- 349 + 31539499 = 31539848
- 409 + 31539439 = 31539848
- 499 + 31539349 = 31539848
- 577 + 31539271 = 31539848
- 607 + 31539241 = 31539848
- 619 + 31539229 = 31539848
Showing the first eight; more decompositions exist.
