Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572056, here are decompositions:

7 + 31572049 = 31572056
73 + 31571983 = 31572056
157 + 31571899 = 31572056
223 + 31571833 = 31572056
277 + 31571779 = 31572056
349 + 31571707 = 31572056
409 + 31571647 = 31572056
487 + 31571569 = 31572056

Showing the first eight; more decompositions exist.
