Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185784, here are decompositions:

17 + 185767 = 185784
31 + 185753 = 185784
37 + 185747 = 185784
47 + 185737 = 185784
61 + 185723 = 185784
73 + 185711 = 185784
101 + 185683 = 185784
103 + 185681 = 185784

Showing the first eight; more decompositions exist.
