Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645224, here are decompositions:

83 + 8645141 = 8645224
101 + 8645123 = 8645224
233 + 8644991 = 8645224
311 + 8644913 = 8645224
443 + 8644781 = 8645224
521 + 8644703 = 8645224
563 + 8644661 = 8645224
617 + 8644607 = 8645224

Showing the first eight; more decompositions exist.
