Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564794, here are decompositions:

13 + 31564781 = 31564794
71 + 31564723 = 31564794
73 + 31564721 = 31564794
137 + 31564657 = 31564794
181 + 31564613 = 31564794
263 + 31564531 = 31564794
277 + 31564517 = 31564794
293 + 31564501 = 31564794

Showing the first eight; more decompositions exist.
