Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503324, here are decompositions:

11 + 31503313 = 31503324
107 + 31503217 = 31503324
157 + 31503167 = 31503324
173 + 31503151 = 31503324
263 + 31503061 = 31503324
271 + 31503053 = 31503324
331 + 31502993 = 31503324
383 + 31502941 = 31503324

Showing the first eight; more decompositions exist.
