Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529606, here are decompositions:

13 + 31529593 = 31529606
67 + 31529539 = 31529606
127 + 31529479 = 31529606
193 + 31529413 = 31529606
337 + 31529269 = 31529606
349 + 31529257 = 31529606
439 + 31529167 = 31529606
457 + 31529149 = 31529606

Showing the first eight; more decompositions exist.
