Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188422, here are decompositions:

5 + 188417 = 188422
53 + 188369 = 188422
71 + 188351 = 188422
89 + 188333 = 188422
131 + 188291 = 188422
149 + 188273 = 188422
173 + 188249 = 188422
233 + 188189 = 188422

Showing the first eight; more decompositions exist.
