Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627152, here are decompositions:

19 + 31627133 = 31627152
31 + 31627121 = 31627152
61 + 31627091 = 31627152
79 + 31627073 = 31627152
83 + 31627069 = 31627152
101 + 31627051 = 31627152
173 + 31626979 = 31627152
269 + 31626883 = 31627152

Showing the first eight; more decompositions exist.
