Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185498, here are decompositions:

7 + 185491 = 185498
31 + 185467 = 185498
97 + 185401 = 185498
127 + 185371 = 185498
139 + 185359 = 185498
199 + 185299 = 185498
277 + 185221 = 185498
331 + 185167 = 185498

Showing the first eight; more decompositions exist.
