Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536030, here are decompositions:
- 11 + 31536019 = 31536030
- 13 + 31536017 = 31536030
- 47 + 31535983 = 31536030
- 83 + 31535947 = 31536030
- 89 + 31535941 = 31536030
- 151 + 31535879 = 31536030
- 199 + 31535831 = 31536030
- 233 + 31535797 = 31536030
Showing the first eight; more decompositions exist.
