Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736278, here are decompositions:

79 + 8736199 = 8736278
139 + 8736139 = 8736278
151 + 8736127 = 8736278
181 + 8736097 = 8736278
241 + 8736037 = 8736278
277 + 8736001 = 8736278
307 + 8735971 = 8736278
337 + 8735941 = 8736278

Showing the first eight; more decompositions exist.
