Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533956, here are decompositions:

7 + 31533949 = 31533956
37 + 31533919 = 31533956
109 + 31533847 = 31533956
127 + 31533829 = 31533956
193 + 31533763 = 31533956
409 + 31533547 = 31533956
439 + 31533517 = 31533956
457 + 31533499 = 31533956

Showing the first eight; more decompositions exist.
