Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13590, here are decompositions:

13 + 13577 = 13590
23 + 13567 = 13590
37 + 13553 = 13590
53 + 13537 = 13590
67 + 13523 = 13590
103 + 13487 = 13590
113 + 13477 = 13590
127 + 13463 = 13590

Showing the first eight; more decompositions exist.
