Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172234, here are decompositions:

11 + 172223 = 172234
17 + 172217 = 172234
53 + 172181 = 172234
107 + 172127 = 172234
137 + 172097 = 172234
233 + 172001 = 172234
311 + 171923 = 172234
317 + 171917 = 172234

Showing the first eight; more decompositions exist.
