Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503522, here are decompositions:

13 + 31503509 = 31503522
53 + 31503469 = 31503522
79 + 31503443 = 31503522
179 + 31503343 = 31503522
181 + 31503341 = 31503522
191 + 31503331 = 31503522
199 + 31503323 = 31503522
263 + 31503259 = 31503522

Showing the first eight; more decompositions exist.
