Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534638, here are decompositions:

7 + 31534631 = 31534638
41 + 31534597 = 31534638
137 + 31534501 = 31534638
151 + 31534487 = 31534638
181 + 31534457 = 31534638
197 + 31534441 = 31534638
211 + 31534427 = 31534638
227 + 31534411 = 31534638

Showing the first eight; more decompositions exist.
