Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647180, here are decompositions:

23 + 8647157 = 8647180
41 + 8647139 = 8647180
53 + 8647127 = 8647180
89 + 8647091 = 8647180
137 + 8647043 = 8647180
149 + 8647031 = 8647180
173 + 8647007 = 8647180
233 + 8646947 = 8647180

Showing the first eight; more decompositions exist.
