Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161716, here are decompositions:

89 + 161627 = 161716
173 + 161543 = 161716
257 + 161459 = 161716
263 + 161453 = 161716
353 + 161363 = 161716
383 + 161333 = 161716
449 + 161267 = 161716
479 + 161237 = 161716

Showing the first eight; more decompositions exist.
