Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185790, here are decompositions:

23 + 185767 = 185790
37 + 185753 = 185790
41 + 185749 = 185790
43 + 185747 = 185790
53 + 185737 = 185790
67 + 185723 = 185790
79 + 185711 = 185790
83 + 185707 = 185790

Showing the first eight; more decompositions exist.
