Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536810, here are decompositions:
- 17 + 31536793 = 31536810
- 37 + 31536773 = 31536810
- 79 + 31536731 = 31536810
- 103 + 31536707 = 31536810
- 113 + 31536697 = 31536810
- 181 + 31536629 = 31536810
- 197 + 31536613 = 31536810
- 271 + 31536539 = 31536810
Showing the first eight; more decompositions exist.
