Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185992, here are decompositions:

5 + 185987 = 185992
41 + 185951 = 185992
89 + 185903 = 185992
173 + 185819 = 185992
179 + 185813 = 185992
239 + 185753 = 185992
269 + 185723 = 185992
281 + 185711 = 185992

Showing the first eight; more decompositions exist.
