Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628550, here are decompositions:

3 + 8628547 = 8628550
71 + 8628479 = 8628550
101 + 8628449 = 8628550
107 + 8628443 = 8628550
167 + 8628383 = 8628550
173 + 8628377 = 8628550
191 + 8628359 = 8628550
197 + 8628353 = 8628550

Showing the first eight; more decompositions exist.
