Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671090, here are decompositions:

23 + 8671067 = 8671090
59 + 8671031 = 8671090
83 + 8671007 = 8671090
101 + 8670989 = 8671090
149 + 8670941 = 8671090
227 + 8670863 = 8671090
317 + 8670773 = 8671090
347 + 8670743 = 8671090

Showing the first eight; more decompositions exist.
