Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536956, here are decompositions:
- 13 + 31536943 = 31536956
- 19 + 31536937 = 31536956
- 109 + 31536847 = 31536956
- 127 + 31536829 = 31536956
- 163 + 31536793 = 31536956
- 223 + 31536733 = 31536956
- 349 + 31536607 = 31536956
- 457 + 31536499 = 31536956
Showing the first eight; more decompositions exist.
