Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628458, here are decompositions:

37 + 8628421 = 8628458
109 + 8628349 = 8628458
271 + 8628187 = 8628458
277 + 8628181 = 8628458
337 + 8628121 = 8628458
409 + 8628049 = 8628458
439 + 8628019 = 8628458
547 + 8627911 = 8628458

Showing the first eight; more decompositions exist.
