Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671538, here are decompositions:

19 + 8671519 = 8671538
37 + 8671501 = 8671538
67 + 8671471 = 8671538
97 + 8671441 = 8671538
157 + 8671381 = 8671538
199 + 8671339 = 8671538
307 + 8671231 = 8671538
439 + 8671099 = 8671538

Showing the first eight; more decompositions exist.
