Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620956, here are decompositions:

13 + 31620943 = 31620956
19 + 31620937 = 31620956
163 + 31620793 = 31620956
193 + 31620763 = 31620956
223 + 31620733 = 31620956
277 + 31620679 = 31620956
379 + 31620577 = 31620956
439 + 31620517 = 31620956

Showing the first eight; more decompositions exist.
