Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627500, here are decompositions:

17 + 31627483 = 31627500
89 + 31627411 = 31627500
109 + 31627391 = 31627500
127 + 31627373 = 31627500
167 + 31627333 = 31627500
181 + 31627319 = 31627500
197 + 31627303 = 31627500
211 + 31627289 = 31627500

Showing the first eight; more decompositions exist.
