Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15582, here are decompositions:

13 + 15569 = 15582
23 + 15559 = 15582
31 + 15551 = 15582
41 + 15541 = 15582
71 + 15511 = 15582
89 + 15493 = 15582
109 + 15473 = 15582
131 + 15451 = 15582

Showing the first eight; more decompositions exist.
