Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671512, here are decompositions:

11 + 8671501 = 8671512
13 + 8671499 = 8671512
41 + 8671471 = 8671512
43 + 8671469 = 8671512
71 + 8671441 = 8671512
103 + 8671409 = 8671512
131 + 8671381 = 8671512
149 + 8671363 = 8671512

Showing the first eight; more decompositions exist.
