Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631828, here are decompositions:

5 + 8631823 = 8631828
41 + 8631787 = 8631828
47 + 8631781 = 8631828
59 + 8631769 = 8631828
199 + 8631629 = 8631828
211 + 8631617 = 8631828
229 + 8631599 = 8631828
311 + 8631517 = 8631828

Showing the first eight; more decompositions exist.
