Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636372, here are decompositions:

103 + 8636269 = 8636372
109 + 8636263 = 8636372
373 + 8635999 = 8636372
421 + 8635951 = 8636372
439 + 8635933 = 8636372
523 + 8635849 = 8636372
643 + 8635729 = 8636372
673 + 8635699 = 8636372

Showing the first eight; more decompositions exist.
