Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185456, here are decompositions:

97 + 185359 = 185456
157 + 185299 = 185456
223 + 185233 = 185456
307 + 185149 = 185456
367 + 185089 = 185456
379 + 185077 = 185456
457 + 184999 = 185456
463 + 184993 = 185456

Showing the first eight; more decompositions exist.
