Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172346, here are decompositions:

3 + 172343 = 172346
67 + 172279 = 172346
103 + 172243 = 172346
127 + 172219 = 172346
193 + 172153 = 172346
199 + 172147 = 172346
277 + 172069 = 172346
337 + 172009 = 172346

Showing the first eight; more decompositions exist.
