Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503164, here are decompositions:

13 + 31503151 = 31503164
61 + 31503103 = 31503164
103 + 31503061 = 31503164
211 + 31502953 = 31503164
223 + 31502941 = 31503164
241 + 31502923 = 31503164
283 + 31502881 = 31503164
307 + 31502857 = 31503164

Showing the first eight; more decompositions exist.
