Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171922, here are decompositions:

5 + 171917 = 171922
41 + 171881 = 171922
53 + 171869 = 171922
59 + 171863 = 171922
71 + 171851 = 171922
251 + 171671 = 171922
263 + 171659 = 171922
269 + 171653 = 171922

Showing the first eight; more decompositions exist.
