Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635628, here are decompositions:

7 + 8635621 = 8635628
61 + 8635567 = 8635628
97 + 8635531 = 8635628
151 + 8635477 = 8635628
277 + 8635351 = 8635628
307 + 8635321 = 8635628
349 + 8635279 = 8635628
367 + 8635261 = 8635628

Showing the first eight; more decompositions exist.
