Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171970, here are decompositions:

23 + 171947 = 171970
41 + 171929 = 171970
47 + 171923 = 171970
53 + 171917 = 171970
89 + 171881 = 171970
101 + 171869 = 171970
107 + 171863 = 171970
167 + 171803 = 171970

Showing the first eight; more decompositions exist.
