Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536870, here are decompositions:
- 7 + 31536863 = 31536870
- 23 + 31536847 = 31536870
- 41 + 31536829 = 31536870
- 47 + 31536823 = 31536870
- 97 + 31536773 = 31536870
- 137 + 31536733 = 31536870
- 139 + 31536731 = 31536870
- 151 + 31536719 = 31536870
Showing the first eight; more decompositions exist.
