Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671540, here are decompositions:

23 + 8671517 = 8671540
29 + 8671511 = 8671540
41 + 8671499 = 8671540
71 + 8671469 = 8671540
83 + 8671457 = 8671540
113 + 8671427 = 8671540
131 + 8671409 = 8671540
173 + 8671367 = 8671540

Showing the first eight; more decompositions exist.
