Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639574, here are decompositions:

7 + 8639567 = 8639574
11 + 8639563 = 8639574
23 + 8639551 = 8639574
43 + 8639531 = 8639574
67 + 8639507 = 8639574
113 + 8639461 = 8639574
131 + 8639443 = 8639574
173 + 8639401 = 8639574

Showing the first eight; more decompositions exist.
