Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172316, here are decompositions:

3 + 172313 = 172316
19 + 172297 = 172316
37 + 172279 = 172316
73 + 172243 = 172316
97 + 172219 = 172316
103 + 172213 = 172316
163 + 172153 = 172316
223 + 172093 = 172316

Showing the first eight; more decompositions exist.
