Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635690, here are decompositions:

3 + 8635687 = 8635690
17 + 8635673 = 8635690
23 + 8635667 = 8635690
53 + 8635637 = 8635690
59 + 8635631 = 8635690
83 + 8635607 = 8635690
131 + 8635559 = 8635690
137 + 8635553 = 8635690

Showing the first eight; more decompositions exist.
