Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628826, here are decompositions:

47 + 8628779 = 8628826
53 + 8628773 = 8628826
149 + 8628677 = 8628826
179 + 8628647 = 8628826
197 + 8628629 = 8628826
347 + 8628479 = 8628826
383 + 8628443 = 8628826
419 + 8628407 = 8628826

Showing the first eight; more decompositions exist.
