Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189636, here are decompositions:

17 + 189619 = 189636
19 + 189617 = 189636
23 + 189613 = 189636
37 + 189599 = 189636
43 + 189593 = 189636
53 + 189583 = 189636
89 + 189547 = 189636
107 + 189529 = 189636

Showing the first eight; more decompositions exist.
