Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77584, here are decompositions:

11 + 77573 = 77584
41 + 77543 = 77584
71 + 77513 = 77584
107 + 77477 = 77584
113 + 77471 = 77584
137 + 77447 = 77584
167 + 77417 = 77584
233 + 77351 = 77584

Showing the first eight; more decompositions exist.
