Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628014, here are decompositions:

3 + 31628011 = 31628014
53 + 31627961 = 31628014
83 + 31627931 = 31628014
251 + 31627763 = 31628014
263 + 31627751 = 31628014
293 + 31627721 = 31628014
503 + 31627511 = 31628014
641 + 31627373 = 31628014

Showing the first eight; more decompositions exist.
