Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671508, here are decompositions:

7 + 8671501 = 8671508
37 + 8671471 = 8671508
61 + 8671447 = 8671508
67 + 8671441 = 8671508
127 + 8671381 = 8671508
277 + 8671231 = 8671508
331 + 8671177 = 8671508
409 + 8671099 = 8671508

Showing the first eight; more decompositions exist.
