Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172022, here are decompositions:

13 + 172009 = 172022
199 + 171823 = 172022
211 + 171811 = 172022
223 + 171799 = 172022
229 + 171793 = 172022
349 + 171673 = 172022
439 + 171583 = 172022
463 + 171559 = 172022

Showing the first eight; more decompositions exist.
