Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628422, here are decompositions:

73 + 8628349 = 8628422
151 + 8628271 = 8628422
241 + 8628181 = 8628422
373 + 8628049 = 8628422
571 + 8627851 = 8628422
613 + 8627809 = 8628422
709 + 8627713 = 8628422
811 + 8627611 = 8628422

Showing the first eight; more decompositions exist.
