Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636572, here are decompositions:

23 + 8636549 = 8636572
29 + 8636543 = 8636572
59 + 8636513 = 8636572
149 + 8636423 = 8636572
311 + 8636261 = 8636572
353 + 8636219 = 8636572
431 + 8636141 = 8636572
443 + 8636129 = 8636572

Showing the first eight; more decompositions exist.
