Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726748, here are decompositions:

11 + 8726737 = 8726748
61 + 8726687 = 8726748
71 + 8726677 = 8726748
101 + 8726647 = 8726748
137 + 8726611 = 8726748
179 + 8726569 = 8726748
227 + 8726521 = 8726748
241 + 8726507 = 8726748

Showing the first eight; more decompositions exist.
