Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185488, here are decompositions:

5 + 185483 = 185488
11 + 185477 = 185488
47 + 185441 = 185488
59 + 185429 = 185488
179 + 185309 = 185488
197 + 185291 = 185488
311 + 185177 = 185488
389 + 185099 = 185488

Showing the first eight; more decompositions exist.
