Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671506, here are decompositions:

5 + 8671501 = 8671506
7 + 8671499 = 8671506
37 + 8671469 = 8671506
43 + 8671463 = 8671506
59 + 8671447 = 8671506
79 + 8671427 = 8671506
97 + 8671409 = 8671506
113 + 8671393 = 8671506

Showing the first eight; more decompositions exist.
