Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539224, here are decompositions:
- 61 + 31539163 = 31539224
- 151 + 31539073 = 31539224
- 163 + 31539061 = 31539224
- 181 + 31539043 = 31539224
- 337 + 31538887 = 31539224
- 397 + 31538827 = 31539224
- 571 + 31538653 = 31539224
- 601 + 31538623 = 31539224
Showing the first eight; more decompositions exist.
