Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171954, here are decompositions:

7 + 171947 = 171954
17 + 171937 = 171954
31 + 171923 = 171954
37 + 171917 = 171954
73 + 171881 = 171954
103 + 171851 = 171954
127 + 171827 = 171954
131 + 171823 = 171954

Showing the first eight; more decompositions exist.
