Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536864, here are decompositions:
- 17 + 31536847 = 31536864
- 41 + 31536823 = 31536864
- 43 + 31536821 = 31536864
- 71 + 31536793 = 31536864
- 131 + 31536733 = 31536864
- 157 + 31536707 = 31536864
- 167 + 31536697 = 31536864
- 251 + 31536613 = 31536864
Showing the first eight; more decompositions exist.
