Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185356, here are decompositions:

29 + 185327 = 185356
47 + 185309 = 185356
53 + 185303 = 185356
89 + 185267 = 185356
113 + 185243 = 185356
167 + 185189 = 185356
173 + 185183 = 185356
179 + 185177 = 185356

Showing the first eight; more decompositions exist.
