Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539576, here are decompositions:

7 + 31539569 = 31539576
53 + 31539523 = 31539576
109 + 31539467 = 31539576
137 + 31539439 = 31539576
163 + 31539413 = 31539576
199 + 31539377 = 31539576
223 + 31539353 = 31539576
227 + 31539349 = 31539576

Showing the first eight; more decompositions exist.
