Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671578, here are decompositions:

5 + 8671573 = 8671578
29 + 8671549 = 8671578
59 + 8671519 = 8671578
61 + 8671517 = 8671578
67 + 8671511 = 8671578
79 + 8671499 = 8671578
107 + 8671471 = 8671578
109 + 8671469 = 8671578

Showing the first eight; more decompositions exist.
