Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624020, here are decompositions:

3 + 8624017 = 8624020
11 + 8624009 = 8624020
17 + 8624003 = 8624020
59 + 8623961 = 8624020
137 + 8623883 = 8624020
173 + 8623847 = 8624020
227 + 8623793 = 8624020
233 + 8623787 = 8624020

Showing the first eight; more decompositions exist.
