Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172408, here are decompositions:

101 + 172307 = 172408
149 + 172259 = 172408
191 + 172217 = 172408
227 + 172181 = 172408
239 + 172169 = 172408
251 + 172157 = 172408
281 + 172127 = 172408
311 + 172097 = 172408

Showing the first eight; more decompositions exist.
