Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672222, here are decompositions:

19 + 8672203 = 8672222
61 + 8672161 = 8672222
241 + 8671981 = 8672222
673 + 8671549 = 8672222
751 + 8671471 = 8672222
829 + 8671393 = 8672222
859 + 8671363 = 8672222
883 + 8671339 = 8672222

Showing the first eight; more decompositions exist.
