Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503456, here are decompositions:

13 + 31503443 = 31503456
113 + 31503343 = 31503456
197 + 31503259 = 31503456
227 + 31503229 = 31503456
239 + 31503217 = 31503456
277 + 31503179 = 31503456
317 + 31503139 = 31503456
337 + 31503119 = 31503456

Showing the first eight; more decompositions exist.
