Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641584, here are decompositions:

13 + 8641571 = 8641584
37 + 8641547 = 8641584
41 + 8641543 = 8641584
43 + 8641541 = 8641584
67 + 8641517 = 8641584
71 + 8641513 = 8641584
113 + 8641471 = 8641584
131 + 8641453 = 8641584

Showing the first eight; more decompositions exist.
