Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600956, here are decompositions:

73 + 31600883 = 31600956
97 + 31600859 = 31600956
113 + 31600843 = 31600956
139 + 31600817 = 31600956
157 + 31600799 = 31600956
173 + 31600783 = 31600956
223 + 31600733 = 31600956
239 + 31600717 = 31600956

Showing the first eight; more decompositions exist.
