Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622, here are decompositions:

13 + 8609 = 8622
23 + 8599 = 8622
41 + 8581 = 8622
59 + 8563 = 8622
79 + 8543 = 8622
83 + 8539 = 8622
101 + 8521 = 8622
109 + 8513 = 8622

Showing the first eight; more decompositions exist.
