Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503316, here are decompositions:

3 + 31503313 = 31503316
107 + 31503209 = 31503316
113 + 31503203 = 31503316
137 + 31503179 = 31503316
149 + 31503167 = 31503316
197 + 31503119 = 31503316
263 + 31503053 = 31503316
353 + 31502963 = 31503316

Showing the first eight; more decompositions exist.
