Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622872, here are decompositions:

19 + 8622853 = 8622872
31 + 8622841 = 8622872
61 + 8622811 = 8622872
79 + 8622793 = 8622872
109 + 8622763 = 8622872
151 + 8622721 = 8622872
373 + 8622499 = 8622872
409 + 8622463 = 8622872

Showing the first eight; more decompositions exist.
