Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15584, here are decompositions:

3 + 15581 = 15584
43 + 15541 = 15584
73 + 15511 = 15584
157 + 15427 = 15584
193 + 15391 = 15584
211 + 15373 = 15584
223 + 15361 = 15584
271 + 15313 = 15584

Showing the first eight; more decompositions exist.
