Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628850, here are decompositions:

3 + 8628847 = 8628850
59 + 8628791 = 8628850
71 + 8628779 = 8628850
173 + 8628677 = 8628850
227 + 8628623 = 8628850
401 + 8628449 = 8628850
443 + 8628407 = 8628850
467 + 8628383 = 8628850

Showing the first eight; more decompositions exist.
