Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171976, here are decompositions:

29 + 171947 = 171976
47 + 171929 = 171976
53 + 171923 = 171976
59 + 171917 = 171976
107 + 171869 = 171976
113 + 171863 = 171976
149 + 171827 = 171976
173 + 171803 = 171976

Showing the first eight; more decompositions exist.
