Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671404, here are decompositions:

11 + 8671393 = 8671404
23 + 8671381 = 8671404
37 + 8671367 = 8671404
41 + 8671363 = 8671404
43 + 8671361 = 8671404
73 + 8671331 = 8671404
83 + 8671321 = 8671404
97 + 8671307 = 8671404

Showing the first eight; more decompositions exist.
