Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2584, here are decompositions:

5 + 2579 = 2584
41 + 2543 = 2584
53 + 2531 = 2584
107 + 2477 = 2584
137 + 2447 = 2584
167 + 2417 = 2584
173 + 2411 = 2584
191 + 2393 = 2584

Showing the first eight; more decompositions exist.
