Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162590, here are decompositions:

13 + 162577 = 162590
37 + 162553 = 162590
61 + 162529 = 162590
67 + 162523 = 162590
73 + 162517 = 162590
97 + 162493 = 162590
139 + 162451 = 162590
151 + 162439 = 162590

Showing the first eight; more decompositions exist.
