Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726918, here are decompositions:

157 + 8726761 = 8726918
181 + 8726737 = 8726918
241 + 8726677 = 8726918
271 + 8726647 = 8726918
307 + 8726611 = 8726918
331 + 8726587 = 8726918
349 + 8726569 = 8726918
397 + 8726521 = 8726918

Showing the first eight; more decompositions exist.
