Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564804, here are decompositions:

23 + 31564781 = 31564804
83 + 31564721 = 31564804
191 + 31564613 = 31564804
443 + 31564361 = 31564804
563 + 31564241 = 31564804
641 + 31564163 = 31564804
647 + 31564157 = 31564804
701 + 31564103 = 31564804

Showing the first eight; more decompositions exist.
