Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645572, here are decompositions:

29 + 8645543 = 8645572
191 + 8645381 = 8645572
311 + 8645261 = 8645572
431 + 8645141 = 8645572
449 + 8645123 = 8645572
491 + 8645081 = 8645572
563 + 8645009 = 8645572
653 + 8644919 = 8645572

Showing the first eight; more decompositions exist.
