Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647102, here are decompositions:

11 + 8647091 = 8647102
41 + 8647061 = 8647102
59 + 8647043 = 8647102
71 + 8647031 = 8647102
131 + 8646971 = 8647102
173 + 8646929 = 8647102
251 + 8646851 = 8647102
281 + 8646821 = 8647102

Showing the first eight; more decompositions exist.
