Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503492, here are decompositions:

23 + 31503469 = 31503492
113 + 31503379 = 31503492
131 + 31503361 = 31503492
149 + 31503343 = 31503492
151 + 31503341 = 31503492
179 + 31503313 = 31503492
233 + 31503259 = 31503492
263 + 31503229 = 31503492

Showing the first eight; more decompositions exist.
