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.
