Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536756, here are decompositions:
- 23 + 31536733 = 31536756
- 37 + 31536719 = 31536756
- 59 + 31536697 = 31536756
- 127 + 31536629 = 31536756
- 149 + 31536607 = 31536756
- 227 + 31536529 = 31536756
- 257 + 31536499 = 31536756
- 353 + 31536403 = 31536756
Showing the first eight; more decompositions exist.
