Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742726, here are decompositions:

37 + 8742689 = 8742726
53 + 8742673 = 8742726
73 + 8742653 = 8742726
89 + 8742637 = 8742726
103 + 8742623 = 8742726
149 + 8742577 = 8742726
197 + 8742529 = 8742726
227 + 8742499 = 8742726

Showing the first eight; more decompositions exist.
