Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503354, here are decompositions:

11 + 31503343 = 31503354
13 + 31503341 = 31503354
17 + 31503337 = 31503354
23 + 31503331 = 31503354
31 + 31503323 = 31503354
41 + 31503313 = 31503354
137 + 31503217 = 31503354
151 + 31503203 = 31503354

Showing the first eight; more decompositions exist.
