Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172326, here are decompositions:

5 + 172321 = 172326
13 + 172313 = 172326
19 + 172307 = 172326
29 + 172297 = 172326
43 + 172283 = 172326
47 + 172279 = 172326
67 + 172259 = 172326
83 + 172243 = 172326

Showing the first eight; more decompositions exist.
