Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510952, here are decompositions:

19 + 31510933 = 31510952
43 + 31510909 = 31510952
61 + 31510891 = 31510952
139 + 31510813 = 31510952
163 + 31510789 = 31510952
181 + 31510771 = 31510952
199 + 31510753 = 31510952
271 + 31510681 = 31510952

Showing the first eight; more decompositions exist.
