Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188358, here are decompositions:

7 + 188351 = 188358
41 + 188317 = 188358
47 + 188311 = 188358
59 + 188299 = 188358
67 + 188291 = 188358
97 + 188261 = 188358
109 + 188249 = 188358
179 + 188179 = 188358

Showing the first eight; more decompositions exist.
