Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15590, here are decompositions:

7 + 15583 = 15590
31 + 15559 = 15590
79 + 15511 = 15590
97 + 15493 = 15590
139 + 15451 = 15590
151 + 15439 = 15590
163 + 15427 = 15590
199 + 15391 = 15590

Showing the first eight; more decompositions exist.
