Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012628, here are decompositions:

31 + 1012597 = 1012628
37 + 1012591 = 1012628
79 + 1012549 = 1012628
109 + 1012519 = 1012628
139 + 1012489 = 1012628
181 + 1012447 = 1012628
229 + 1012399 = 1012628
307 + 1012321 = 1012628

Showing the first eight; more decompositions exist.
