Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171254, here are decompositions:

3 + 171251 = 171254
151 + 171103 = 171254
163 + 171091 = 171254
211 + 171043 = 171254
283 + 170971 = 171254
367 + 170887 = 171254
373 + 170881 = 171254
397 + 170857 = 171254

Showing the first eight; more decompositions exist.
