Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503012, here are decompositions:

19 + 31502993 = 31503012
53 + 31502959 = 31503012
59 + 31502953 = 31503012
71 + 31502941 = 31503012
89 + 31502923 = 31503012
131 + 31502881 = 31503012
251 + 31502761 = 31503012
269 + 31502743 = 31503012

Showing the first eight; more decompositions exist.
