Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726942, here are decompositions:

19 + 8726923 = 8726942
79 + 8726863 = 8726942
139 + 8726803 = 8726942
181 + 8726761 = 8726942
229 + 8726713 = 8726942
271 + 8726671 = 8726942
331 + 8726611 = 8726942
373 + 8726569 = 8726942

Showing the first eight; more decompositions exist.
