Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503474, here are decompositions:

5 + 31503469 = 31503474
31 + 31503443 = 31503474
113 + 31503361 = 31503474
131 + 31503343 = 31503474
137 + 31503337 = 31503474
151 + 31503323 = 31503474
257 + 31503217 = 31503474
271 + 31503203 = 31503474

Showing the first eight; more decompositions exist.
