Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189520, here are decompositions:

3 + 189517 = 189520
11 + 189509 = 189520
29 + 189491 = 189520
41 + 189479 = 189520
47 + 189473 = 189520
53 + 189467 = 189520
83 + 189437 = 189520
113 + 189407 = 189520

Showing the first eight; more decompositions exist.
