Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185528, here are decompositions:

37 + 185491 = 185528
61 + 185467 = 185528
127 + 185401 = 185528
157 + 185371 = 185528
229 + 185299 = 185528
307 + 185221 = 185528
367 + 185161 = 185528
379 + 185149 = 185528

Showing the first eight; more decompositions exist.
