Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627666, here are decompositions:

97 + 8627569 = 8627666
139 + 8627527 = 8627666
163 + 8627503 = 8627666
193 + 8627473 = 8627666
199 + 8627467 = 8627666
337 + 8627329 = 8627666
367 + 8627299 = 8627666
409 + 8627257 = 8627666

Showing the first eight; more decompositions exist.
