Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628648, here are decompositions:

5 + 8628643 = 8628648
19 + 8628629 = 8628648
47 + 8628601 = 8628648
97 + 8628551 = 8628648
101 + 8628547 = 8628648
167 + 8628481 = 8628648
199 + 8628449 = 8628648
227 + 8628421 = 8628648

Showing the first eight; more decompositions exist.
