Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536102, here are decompositions:

5 + 31536097 = 31536102
41 + 31536061 = 31536102
53 + 31536049 = 31536102
83 + 31536019 = 31536102
163 + 31535939 = 31536102
193 + 31535909 = 31536102
223 + 31535879 = 31536102
271 + 31535831 = 31536102

Showing the first eight; more decompositions exist.
