Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539068, here are decompositions:
- 7 + 31539061 = 31539068
- 61 + 31539007 = 31539068
- 181 + 31538887 = 31539068
- 241 + 31538827 = 31539068
- 349 + 31538719 = 31539068
- 397 + 31538671 = 31539068
- 439 + 31538629 = 31539068
- 487 + 31538581 = 31539068
Showing the first eight; more decompositions exist.
