Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628040, here are decompositions:

23 + 8628017 = 8628040
53 + 8627987 = 8628040
101 + 8627939 = 8628040
131 + 8627909 = 8628040
137 + 8627903 = 8628040
173 + 8627867 = 8628040
227 + 8627813 = 8628040
233 + 8627807 = 8628040

Showing the first eight; more decompositions exist.
