Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559794, here are decompositions:

11 + 31559783 = 31559794
17 + 31559777 = 31559794
23 + 31559771 = 31559794
107 + 31559687 = 31559794
113 + 31559681 = 31559794
257 + 31559537 = 31559794
293 + 31559501 = 31559794
347 + 31559447 = 31559794

Showing the first eight; more decompositions exist.
