Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637028, here are decompositions:

11 + 8637017 = 8637028
41 + 8636987 = 8637028
107 + 8636921 = 8637028
227 + 8636801 = 8637028
269 + 8636759 = 8637028
401 + 8636627 = 8637028
479 + 8636549 = 8637028
641 + 8636387 = 8637028

Showing the first eight; more decompositions exist.
