Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171616, here are decompositions:

149 + 171467 = 171616
167 + 171449 = 171616
233 + 171383 = 171616
317 + 171299 = 171616
353 + 171263 = 171616
383 + 171233 = 171616
449 + 171167 = 171616
563 + 171053 = 171616

Showing the first eight; more decompositions exist.
