Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628454, here are decompositions:

5 + 8628449 = 8628454
11 + 8628443 = 8628454
47 + 8628407 = 8628454
71 + 8628383 = 8628454
101 + 8628353 = 8628454
251 + 8628203 = 8628454
281 + 8628173 = 8628454
293 + 8628161 = 8628454

Showing the first eight; more decompositions exist.
