Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503594, here are decompositions:

37 + 31503557 = 31503594
41 + 31503553 = 31503594
151 + 31503443 = 31503594
233 + 31503361 = 31503594
251 + 31503343 = 31503594
257 + 31503337 = 31503594
263 + 31503331 = 31503594
271 + 31503323 = 31503594

Showing the first eight; more decompositions exist.
