Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171942, here are decompositions:

5 + 171937 = 171942
13 + 171929 = 171942
19 + 171923 = 171942
53 + 171889 = 171942
61 + 171881 = 171942
73 + 171869 = 171942
79 + 171863 = 171942
131 + 171811 = 171942

Showing the first eight; more decompositions exist.
