Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671522, here are decompositions:

3 + 8671519 = 8671522
5 + 8671517 = 8671522
11 + 8671511 = 8671522
23 + 8671499 = 8671522
53 + 8671469 = 8671522
59 + 8671463 = 8671522
113 + 8671409 = 8671522
191 + 8671331 = 8671522

Showing the first eight; more decompositions exist.
