Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185378, here are decompositions:

7 + 185371 = 185378
19 + 185359 = 185378
79 + 185299 = 185378
157 + 185221 = 185378
211 + 185167 = 185378
229 + 185149 = 185378
241 + 185137 = 185378
307 + 185071 = 185378

Showing the first eight; more decompositions exist.
