Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171224, here are decompositions:

61 + 171163 = 171224
181 + 171043 = 171224
271 + 170953 = 171224
337 + 170887 = 171224
367 + 170857 = 171224
373 + 170851 = 171224
397 + 170827 = 171224
457 + 170767 = 171224

Showing the first eight; more decompositions exist.
