Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171874, here are decompositions:

5 + 171869 = 171874
11 + 171863 = 171874
23 + 171851 = 171874
47 + 171827 = 171874
71 + 171803 = 171874
113 + 171761 = 171874
167 + 171707 = 171874
233 + 171641 = 171874

Showing the first eight; more decompositions exist.
