Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502964, here are decompositions:

5 + 31502959 = 31502964
11 + 31502953 = 31502964
23 + 31502941 = 31502964
37 + 31502927 = 31502964
41 + 31502923 = 31502964
67 + 31502897 = 31502964
83 + 31502881 = 31502964
107 + 31502857 = 31502964

Showing the first eight; more decompositions exist.
