Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172332, here are decompositions:

11 + 172321 = 172332
19 + 172313 = 172332
53 + 172279 = 172332
73 + 172259 = 172332
89 + 172243 = 172332
109 + 172223 = 172332
113 + 172219 = 172332
151 + 172181 = 172332

Showing the first eight; more decompositions exist.
