Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503468, here are decompositions:

89 + 31503379 = 31503468
107 + 31503361 = 31503468
127 + 31503341 = 31503468
131 + 31503337 = 31503468
137 + 31503331 = 31503468
239 + 31503229 = 31503468
251 + 31503217 = 31503468
317 + 31503151 = 31503468

Showing the first eight; more decompositions exist.
