Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619628, here are decompositions:

5 + 8619623 = 8619628
41 + 8619587 = 8619628
89 + 8619539 = 8619628
137 + 8619491 = 8619628
167 + 8619461 = 8619628
191 + 8619437 = 8619628
197 + 8619431 = 8619628
359 + 8619269 = 8619628

Showing the first eight; more decompositions exist.
