Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527696, here are decompositions:
- 7 + 31527689 = 31527696
- 19 + 31527677 = 31527696
- 37 + 31527659 = 31527696
- 113 + 31527583 = 31527696
- 127 + 31527569 = 31527696
- 163 + 31527533 = 31527696
- 173 + 31527523 = 31527696
- 197 + 31527499 = 31527696
Showing the first eight; more decompositions exist.
