Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38620, here are decompositions:

11 + 38609 = 38620
17 + 38603 = 38620
53 + 38567 = 38620
59 + 38561 = 38620
167 + 38453 = 38620
173 + 38447 = 38620
227 + 38393 = 38620
269 + 38351 = 38620

Showing the first eight; more decompositions exist.
