Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628472, here are decompositions:

23 + 8628449 = 8628472
29 + 8628443 = 8628472
89 + 8628383 = 8628472
113 + 8628359 = 8628472
179 + 8628293 = 8628472
239 + 8628233 = 8628472
269 + 8628203 = 8628472
311 + 8628161 = 8628472

Showing the first eight; more decompositions exist.
