Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636442, here are decompositions:

19 + 8636423 = 8636442
53 + 8636389 = 8636442
173 + 8636269 = 8636442
179 + 8636263 = 8636442
181 + 8636261 = 8636442
223 + 8636219 = 8636442
313 + 8636129 = 8636442
349 + 8636093 = 8636442

Showing the first eight; more decompositions exist.
