Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627386, here are decompositions:

23 + 8627363 = 8627386
29 + 8627357 = 8627386
233 + 8627153 = 8627386
239 + 8627147 = 8627386
353 + 8627033 = 8627386
563 + 8626823 = 8627386
653 + 8626733 = 8627386
743 + 8626643 = 8627386

Showing the first eight; more decompositions exist.
