Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502976, here are decompositions:

13 + 31502963 = 31502976
17 + 31502959 = 31502976
23 + 31502953 = 31502976
53 + 31502923 = 31502976
79 + 31502897 = 31502976
199 + 31502777 = 31502976
233 + 31502743 = 31502976
277 + 31502699 = 31502976

Showing the first eight; more decompositions exist.
