Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536960, here are decompositions:
- 17 + 31536943 = 31536960
- 23 + 31536937 = 31536960
- 43 + 31536917 = 31536960
- 89 + 31536871 = 31536960
- 97 + 31536863 = 31536960
- 113 + 31536847 = 31536960
- 131 + 31536829 = 31536960
- 137 + 31536823 = 31536960
Showing the first eight; more decompositions exist.
