Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672786, here are decompositions:

7 + 8672779 = 8672786
13 + 8672773 = 8672786
19 + 8672767 = 8672786
79 + 8672707 = 8672786
127 + 8672659 = 8672786
139 + 8672647 = 8672786
223 + 8672563 = 8672786
277 + 8672509 = 8672786

Showing the first eight; more decompositions exist.
