Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185798, here are decompositions:

31 + 185767 = 185798
61 + 185737 = 185798
157 + 185641 = 185798
199 + 185599 = 185798
229 + 185569 = 185798
241 + 185557 = 185798
271 + 185527 = 185798
307 + 185491 = 185798

Showing the first eight; more decompositions exist.
