Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12590, here are decompositions:

7 + 12583 = 12590
13 + 12577 = 12590
37 + 12553 = 12590
43 + 12547 = 12590
73 + 12517 = 12590
79 + 12511 = 12590
103 + 12487 = 12590
139 + 12451 = 12590

Showing the first eight; more decompositions exist.
