Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172176, here are decompositions:

5 + 172171 = 172176
7 + 172169 = 172176
19 + 172157 = 172176
23 + 172153 = 172176
29 + 172147 = 172176
79 + 172097 = 172176
83 + 172093 = 172176
97 + 172079 = 172176

Showing the first eight; more decompositions exist.
