Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645782, here are decompositions:

23 + 8645759 = 8645782
53 + 8645729 = 8645782
113 + 8645669 = 8645782
149 + 8645633 = 8645782
239 + 8645543 = 8645782
401 + 8645381 = 8645782
521 + 8645261 = 8645782
641 + 8645141 = 8645782

Showing the first eight; more decompositions exist.
