Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726828, here are decompositions:

67 + 8726761 = 8726828
151 + 8726677 = 8726828
157 + 8726671 = 8726828
181 + 8726647 = 8726828
241 + 8726587 = 8726828
307 + 8726521 = 8726828
349 + 8726479 = 8726828
367 + 8726461 = 8726828

Showing the first eight; more decompositions exist.
