Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18584, here are decompositions:

31 + 18553 = 18584
43 + 18541 = 18584
61 + 18523 = 18584
67 + 18517 = 18584
103 + 18481 = 18584
127 + 18457 = 18584
151 + 18433 = 18584
157 + 18427 = 18584

Showing the first eight; more decompositions exist.
