Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503108, here are decompositions:

5 + 31503103 = 31503108
47 + 31503061 = 31503108
149 + 31502959 = 31503108
167 + 31502941 = 31503108
181 + 31502927 = 31503108
211 + 31502897 = 31503108
227 + 31502881 = 31503108
251 + 31502857 = 31503108

Showing the first eight; more decompositions exist.
