Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647330, here are decompositions:

53 + 8647277 = 8647330
101 + 8647229 = 8647330
137 + 8647193 = 8647330
149 + 8647181 = 8647330
173 + 8647157 = 8647330
191 + 8647139 = 8647330
239 + 8647091 = 8647330
269 + 8647061 = 8647330

Showing the first eight; more decompositions exist.
