Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536930, here are decompositions:
- 13 + 31536917 = 31536930
- 59 + 31536871 = 31536930
- 67 + 31536863 = 31536930
- 83 + 31536847 = 31536930
- 101 + 31536829 = 31536930
- 107 + 31536823 = 31536930
- 109 + 31536821 = 31536930
- 137 + 31536793 = 31536930
Showing the first eight; more decompositions exist.
