Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502966, here are decompositions:

3 + 31502963 = 31502966
7 + 31502959 = 31502966
13 + 31502953 = 31502966
43 + 31502923 = 31502966
109 + 31502857 = 31502966
223 + 31502743 = 31502966
277 + 31502689 = 31502966
307 + 31502659 = 31502966

Showing the first eight; more decompositions exist.
