Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620628, here are decompositions:

7 + 8620621 = 8620628
61 + 8620567 = 8620628
199 + 8620429 = 8620628
397 + 8620231 = 8620628
409 + 8620219 = 8620628
439 + 8620189 = 8620628
487 + 8620141 = 8620628
631 + 8619997 = 8620628

Showing the first eight; more decompositions exist.
