Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671518, here are decompositions:

7 + 8671511 = 8671518
17 + 8671501 = 8671518
19 + 8671499 = 8671518
47 + 8671471 = 8671518
61 + 8671457 = 8671518
71 + 8671447 = 8671518
109 + 8671409 = 8671518
137 + 8671381 = 8671518

Showing the first eight; more decompositions exist.
