Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639584, here are decompositions:

17 + 8639567 = 8639584
53 + 8639531 = 8639584
131 + 8639453 = 8639584
293 + 8639291 = 8639584
311 + 8639273 = 8639584
431 + 8639153 = 8639584
461 + 8639123 = 8639584
521 + 8639063 = 8639584

Showing the first eight; more decompositions exist.
