Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536920, here are decompositions:
- 3 + 31536917 = 31536920
- 73 + 31536847 = 31536920
- 97 + 31536823 = 31536920
- 127 + 31536793 = 31536920
- 223 + 31536697 = 31536920
- 307 + 31536613 = 31536920
- 313 + 31536607 = 31536920
- 421 + 31536499 = 31536920
Showing the first eight; more decompositions exist.
