Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525644, here are decompositions:

37 + 31525607 = 31525644
41 + 31525603 = 31525644
43 + 31525601 = 31525644
107 + 31525537 = 31525644
167 + 31525477 = 31525644
197 + 31525447 = 31525644
223 + 31525421 = 31525644
277 + 31525367 = 31525644

Showing the first eight; more decompositions exist.
