Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172310, here are decompositions:

3 + 172307 = 172310
13 + 172297 = 172310
31 + 172279 = 172310
67 + 172243 = 172310
97 + 172213 = 172310
139 + 172171 = 172310
157 + 172153 = 172310
163 + 172147 = 172310

Showing the first eight; more decompositions exist.
