Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671524, here are decompositions:

5 + 8671519 = 8671524
7 + 8671517 = 8671524
13 + 8671511 = 8671524
23 + 8671501 = 8671524
53 + 8671471 = 8671524
61 + 8671463 = 8671524
67 + 8671457 = 8671524
83 + 8671441 = 8671524

Showing the first eight; more decompositions exist.
