Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596576, here are decompositions:

5 + 31596571 = 31596576
23 + 31596553 = 31596576
79 + 31596497 = 31596576
103 + 31596473 = 31596576
139 + 31596437 = 31596576
157 + 31596419 = 31596576
163 + 31596413 = 31596576
173 + 31596403 = 31596576

Showing the first eight; more decompositions exist.
