Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17620, here are decompositions:

11 + 17609 = 17620
23 + 17597 = 17620
41 + 17579 = 17620
47 + 17573 = 17620
101 + 17519 = 17620
131 + 17489 = 17620
137 + 17483 = 17620
149 + 17471 = 17620

Showing the first eight; more decompositions exist.
