Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172030, here are decompositions:

3 + 172027 = 172030
29 + 172001 = 172030
83 + 171947 = 172030
101 + 171929 = 172030
107 + 171923 = 172030
113 + 171917 = 172030
149 + 171881 = 172030
167 + 171863 = 172030

Showing the first eight; more decompositions exist.
