Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636530, here are decompositions:

17 + 8636513 = 8636530
107 + 8636423 = 8636530
269 + 8636261 = 8636530
293 + 8636237 = 8636530
311 + 8636219 = 8636530
389 + 8636141 = 8636530
401 + 8636129 = 8636530
443 + 8636087 = 8636530

Showing the first eight; more decompositions exist.
