Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529468, here are decompositions:

37 + 31529431 = 31529468
109 + 31529359 = 31529468
199 + 31529269 = 31529468
211 + 31529257 = 31529468
379 + 31529089 = 31529468
499 + 31528969 = 31529468
661 + 31528807 = 31529468
727 + 31528741 = 31529468

Showing the first eight; more decompositions exist.
