Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628386, here are decompositions:

3 + 8628383 = 8628386
37 + 8628349 = 8628386
199 + 8628187 = 8628386
229 + 8628157 = 8628386
337 + 8628049 = 8628386
367 + 8628019 = 8628386
379 + 8628007 = 8628386
409 + 8627977 = 8628386

Showing the first eight; more decompositions exist.
