Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536156, here are decompositions:

59 + 31536097 = 31536156
103 + 31536053 = 31536156
107 + 31536049 = 31536156
137 + 31536019 = 31536156
139 + 31536017 = 31536156
173 + 31535983 = 31536156
277 + 31535879 = 31536156
347 + 31535809 = 31536156

Showing the first eight; more decompositions exist.
