Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503422, here are decompositions:

43 + 31503379 = 31503422
61 + 31503361 = 31503422
79 + 31503343 = 31503422
109 + 31503313 = 31503422
163 + 31503259 = 31503422
193 + 31503229 = 31503422
241 + 31503181 = 31503422
271 + 31503151 = 31503422

Showing the first eight; more decompositions exist.
