Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171814, here are decompositions:

3 + 171811 = 171814
11 + 171803 = 171814
53 + 171761 = 171814
101 + 171713 = 171814
107 + 171707 = 171814
173 + 171641 = 171814
197 + 171617 = 171814
347 + 171467 = 171814

Showing the first eight; more decompositions exist.
