Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647338, here are decompositions:

61 + 8647277 = 8647338
107 + 8647231 = 8647338
109 + 8647229 = 8647338
157 + 8647181 = 8647338
181 + 8647157 = 8647338
199 + 8647139 = 8647338
211 + 8647127 = 8647338
277 + 8647061 = 8647338

Showing the first eight; more decompositions exist.
