Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536072, here are decompositions:

11 + 31536061 = 31536072
19 + 31536053 = 31536072
23 + 31536049 = 31536072
53 + 31536019 = 31536072
89 + 31535983 = 31536072
131 + 31535941 = 31536072
163 + 31535909 = 31536072
193 + 31535879 = 31536072

Showing the first eight; more decompositions exist.
