Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8584, here are decompositions:

3 + 8581 = 8584
11 + 8573 = 8584
41 + 8543 = 8584
47 + 8537 = 8584
71 + 8513 = 8584
83 + 8501 = 8584
137 + 8447 = 8584
197 + 8387 = 8584

Showing the first eight; more decompositions exist.
