Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185448, here are decompositions:

7 + 185441 = 185448
19 + 185429 = 185448
47 + 185401 = 185448
79 + 185369 = 185448
89 + 185359 = 185448
139 + 185309 = 185448
149 + 185299 = 185448
157 + 185291 = 185448

Showing the first eight; more decompositions exist.
