Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159520, here are decompositions:

17 + 159503 = 159520
29 + 159491 = 159520
47 + 159473 = 159520
83 + 159437 = 159520
89 + 159431 = 159520
113 + 159407 = 159520
131 + 159389 = 159520
173 + 159347 = 159520

Showing the first eight; more decompositions exist.
