Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537456, here are decompositions:

23 + 31537433 = 31537456
47 + 31537409 = 31537456
149 + 31537307 = 31537456
227 + 31537229 = 31537456
233 + 31537223 = 31537456
359 + 31537097 = 31537456
593 + 31536863 = 31537456
683 + 31536773 = 31537456

Showing the first eight; more decompositions exist.
