Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172622, here are decompositions:

3 + 172619 = 172622
19 + 172603 = 172622
61 + 172561 = 172622
103 + 172519 = 172622
181 + 172441 = 172622
199 + 172423 = 172622
211 + 172411 = 172622
223 + 172399 = 172622

Showing the first eight; more decompositions exist.
