Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628356, here are decompositions:

3 + 8628353 = 8628356
7 + 8628349 = 8628356
199 + 8628157 = 8628356
307 + 8628049 = 8628356
337 + 8628019 = 8628356
349 + 8628007 = 8628356
379 + 8627977 = 8628356
409 + 8627947 = 8628356

Showing the first eight; more decompositions exist.
