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.
