Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677928, here are decompositions:

37 + 8677891 = 8677928
157 + 8677771 = 8677928
277 + 8677651 = 8677928
541 + 8677387 = 8677928
631 + 8677297 = 8677928
661 + 8677267 = 8677928
757 + 8677171 = 8677928
877 + 8677051 = 8677928

Showing the first eight; more decompositions exist.
