Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171784, here are decompositions:

23 + 171761 = 171784
71 + 171713 = 171784
113 + 171671 = 171784
131 + 171653 = 171784
167 + 171617 = 171784
293 + 171491 = 171784
311 + 171473 = 171784
317 + 171467 = 171784

Showing the first eight; more decompositions exist.
