Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673128, here are decompositions:

7 + 8673121 = 8673128
19 + 8673109 = 8673128
31 + 8673097 = 8673128
109 + 8673019 = 8673128
181 + 8672947 = 8673128
307 + 8672821 = 8673128
337 + 8672791 = 8673128
349 + 8672779 = 8673128

Showing the first eight; more decompositions exist.
