Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503126, here are decompositions:

7 + 31503119 = 31503126
19 + 31503107 = 31503126
23 + 31503103 = 31503126
73 + 31503053 = 31503126
163 + 31502963 = 31503126
167 + 31502959 = 31503126
173 + 31502953 = 31503126
199 + 31502927 = 31503126

Showing the first eight; more decompositions exist.
