Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536078, here are decompositions:
- 17 + 31536061 = 31536078
- 29 + 31536049 = 31536078
- 59 + 31536019 = 31536078
- 61 + 31536017 = 31536078
- 97 + 31535981 = 31536078
- 131 + 31535947 = 31536078
- 137 + 31535941 = 31536078
- 139 + 31535939 = 31536078
Showing the first eight; more decompositions exist.
