Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536894, here are decompositions:
- 23 + 31536871 = 31536894
- 31 + 31536863 = 31536894
- 47 + 31536847 = 31536894
- 71 + 31536823 = 31536894
- 73 + 31536821 = 31536894
- 101 + 31536793 = 31536894
- 163 + 31536731 = 31536894
- 197 + 31536697 = 31536894
Showing the first eight; more decompositions exist.
