Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172356, here are decompositions:

5 + 172351 = 172356
13 + 172343 = 172356
43 + 172313 = 172356
59 + 172297 = 172356
73 + 172283 = 172356
97 + 172259 = 172356
113 + 172243 = 172356
137 + 172219 = 172356

Showing the first eight; more decompositions exist.
