Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628112, here are decompositions:

5 + 8628107 = 8628112
173 + 8627939 = 8628112
419 + 8627693 = 8628112
431 + 8627681 = 8628112
503 + 8627609 = 8628112
509 + 8627603 = 8628112
599 + 8627513 = 8628112
683 + 8627429 = 8628112

Showing the first eight; more decompositions exist.
