Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672790, here are decompositions:

11 + 8672779 = 8672790
17 + 8672773 = 8672790
23 + 8672767 = 8672790
59 + 8672731 = 8672790
67 + 8672723 = 8672790
83 + 8672707 = 8672790
103 + 8672687 = 8672790
131 + 8672659 = 8672790

Showing the first eight; more decompositions exist.
