Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536162, here are decompositions:

61 + 31536101 = 31536162
101 + 31536061 = 31536162
109 + 31536053 = 31536162
113 + 31536049 = 31536162
179 + 31535983 = 31536162
181 + 31535981 = 31536162
223 + 31535939 = 31536162
283 + 31535879 = 31536162

Showing the first eight; more decompositions exist.
