Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172222, here are decompositions:

3 + 172219 = 172222
5 + 172217 = 172222
23 + 172199 = 172222
41 + 172181 = 172222
53 + 172169 = 172222
173 + 172049 = 172222
191 + 172031 = 172222
293 + 171929 = 172222

Showing the first eight; more decompositions exist.
