Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633628, here are decompositions:

61 + 8633567 = 8633628
139 + 8633489 = 8633628
167 + 8633461 = 8633628
197 + 8633431 = 8633628
239 + 8633389 = 8633628
251 + 8633377 = 8633628
257 + 8633371 = 8633628
281 + 8633347 = 8633628

Showing the first eight; more decompositions exist.
