Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566950, here are decompositions:

31 + 31566919 = 31566950
157 + 31566793 = 31566950
241 + 31566709 = 31566950
409 + 31566541 = 31566950
433 + 31566517 = 31566950
463 + 31566487 = 31566950
523 + 31566427 = 31566950
601 + 31566349 = 31566950

Showing the first eight; more decompositions exist.
