Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172344, here are decompositions:

13 + 172331 = 172344
23 + 172321 = 172344
31 + 172313 = 172344
37 + 172307 = 172344
47 + 172297 = 172344
61 + 172283 = 172344
101 + 172243 = 172344
127 + 172217 = 172344

Showing the first eight; more decompositions exist.
