Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559692, here are decompositions:

5 + 31559687 = 31559692
11 + 31559681 = 31559692
41 + 31559651 = 31559692
53 + 31559639 = 31559692
191 + 31559501 = 31559692
503 + 31559189 = 31559692
599 + 31559093 = 31559692
641 + 31559051 = 31559692

Showing the first eight; more decompositions exist.
