Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503122, here are decompositions:

3 + 31503119 = 31503122
19 + 31503103 = 31503122
61 + 31503061 = 31503122
163 + 31502959 = 31503122
181 + 31502941 = 31503122
199 + 31502923 = 31503122
241 + 31502881 = 31503122
379 + 31502743 = 31503122

Showing the first eight; more decompositions exist.
