Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85590, here are decompositions:

13 + 85577 = 85590
19 + 85571 = 85590
41 + 85549 = 85590
59 + 85531 = 85590
67 + 85523 = 85590
73 + 85517 = 85590
103 + 85487 = 85590
137 + 85453 = 85590

Showing the first eight; more decompositions exist.
