Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639000, here are decompositions:

3 + 8638997 = 8639000
67 + 8638933 = 8639000
109 + 8638891 = 8639000
151 + 8638849 = 8639000
157 + 8638843 = 8639000
193 + 8638807 = 8639000
313 + 8638687 = 8639000
367 + 8638633 = 8639000

Showing the first eight; more decompositions exist.
