Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172370, here are decompositions:

13 + 172357 = 172370
19 + 172351 = 172370
73 + 172297 = 172370
127 + 172243 = 172370
151 + 172219 = 172370
157 + 172213 = 172370
199 + 172171 = 172370
223 + 172147 = 172370

Showing the first eight; more decompositions exist.
