Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526264, here are decompositions:

37 + 31526227 = 31526264
43 + 31526221 = 31526264
67 + 31526197 = 31526264
73 + 31526191 = 31526264
181 + 31526083 = 31526264
283 + 31525981 = 31526264
307 + 31525957 = 31526264
313 + 31525951 = 31526264

Showing the first eight; more decompositions exist.
