Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503124, here are decompositions:

5 + 31503119 = 31503124
17 + 31503107 = 31503124
71 + 31503053 = 31503124
131 + 31502993 = 31503124
197 + 31502927 = 31503124
227 + 31502897 = 31503124
347 + 31502777 = 31503124
563 + 31502561 = 31503124

Showing the first eight; more decompositions exist.
