Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628266, here are decompositions:

79 + 8628187 = 8628266
109 + 8628157 = 8628266
313 + 8627953 = 8628266
373 + 8627893 = 8628266
433 + 8627833 = 8628266
457 + 8627809 = 8628266
733 + 8627533 = 8628266
739 + 8627527 = 8628266

Showing the first eight; more decompositions exist.
