Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172232, here are decompositions:

13 + 172219 = 172232
19 + 172213 = 172232
61 + 172171 = 172232
79 + 172153 = 172232
139 + 172093 = 172232
163 + 172069 = 172232
211 + 172021 = 172232
223 + 172009 = 172232

Showing the first eight; more decompositions exist.
