Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503516, here are decompositions:

7 + 31503509 = 31503516
47 + 31503469 = 31503516
73 + 31503443 = 31503516
137 + 31503379 = 31503516
173 + 31503343 = 31503516
179 + 31503337 = 31503516
193 + 31503323 = 31503516
257 + 31503259 = 31503516

Showing the first eight; more decompositions exist.
