Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188222, here are decompositions:

43 + 188179 = 188222
79 + 188143 = 188222
193 + 188029 = 188222
211 + 188011 = 188222
271 + 187951 = 188222
313 + 187909 = 188222
379 + 187843 = 188222
523 + 187699 = 188222

Showing the first eight; more decompositions exist.
