Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185426, here are decompositions:

67 + 185359 = 185426
103 + 185323 = 185426
127 + 185299 = 185426
193 + 185233 = 185426
277 + 185149 = 185426
337 + 185089 = 185426
349 + 185077 = 185426
433 + 184993 = 185426

Showing the first eight; more decompositions exist.
