Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536036, here are decompositions:

17 + 31536019 = 31536036
19 + 31536017 = 31536036
53 + 31535983 = 31536036
89 + 31535947 = 31536036
97 + 31535939 = 31536036
127 + 31535909 = 31536036
157 + 31535879 = 31536036
227 + 31535809 = 31536036

Showing the first eight; more decompositions exist.
