Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647210, here are decompositions:

17 + 8647193 = 8647210
29 + 8647181 = 8647210
53 + 8647157 = 8647210
71 + 8647139 = 8647210
83 + 8647127 = 8647210
149 + 8647061 = 8647210
167 + 8647043 = 8647210
179 + 8647031 = 8647210

Showing the first eight; more decompositions exist.
