Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185382, here are decompositions:

11 + 185371 = 185382
13 + 185369 = 185382
19 + 185363 = 185382
23 + 185359 = 185382
59 + 185323 = 185382
73 + 185309 = 185382
79 + 185303 = 185382
83 + 185299 = 185382

Showing the first eight; more decompositions exist.
