Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671026, here are decompositions:

17 + 8671009 = 8671026
19 + 8671007 = 8671026
29 + 8670997 = 8671026
37 + 8670989 = 8671026
79 + 8670947 = 8671026
83 + 8670943 = 8671026
107 + 8670919 = 8671026
139 + 8670887 = 8671026

Showing the first eight; more decompositions exist.
