Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628772, here are decompositions:

149 + 8628623 = 8628772
293 + 8628479 = 8628772
389 + 8628383 = 8628772
419 + 8628353 = 8628772
479 + 8628293 = 8628772
569 + 8628203 = 8628772
599 + 8628173 = 8628772
641 + 8628131 = 8628772

Showing the first eight; more decompositions exist.
