Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596502, here are decompositions:

5 + 31596497 = 31596502
29 + 31596473 = 31596502
83 + 31596419 = 31596502
89 + 31596413 = 31596502
101 + 31596401 = 31596502
191 + 31596311 = 31596502
293 + 31596209 = 31596502
359 + 31596143 = 31596502

Showing the first eight; more decompositions exist.
