Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633540, here are decompositions:

79 + 8633461 = 8633540
109 + 8633431 = 8633540
127 + 8633413 = 8633540
151 + 8633389 = 8633540
163 + 8633377 = 8633540
193 + 8633347 = 8633540
229 + 8633311 = 8633540
373 + 8633167 = 8633540

Showing the first eight; more decompositions exist.
