Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977628, here are decompositions:

17 + 977611 = 977628
19 + 977609 = 977628
37 + 977591 = 977628
61 + 977567 = 977628
89 + 977539 = 977628
107 + 977521 = 977628
181 + 977447 = 977628
191 + 977437 = 977628

Showing the first eight; more decompositions exist.
