Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503226, here are decompositions:

17 + 31503209 = 31503226
23 + 31503203 = 31503226
47 + 31503179 = 31503226
59 + 31503167 = 31503226
107 + 31503119 = 31503226
173 + 31503053 = 31503226
233 + 31502993 = 31503226
263 + 31502963 = 31503226

Showing the first eight; more decompositions exist.
