Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171392, here are decompositions:

139 + 171253 = 171392
223 + 171169 = 171392
229 + 171163 = 171392
313 + 171079 = 171392
349 + 171043 = 171392
421 + 170971 = 171392
439 + 170953 = 171392
541 + 170851 = 171392

Showing the first eight; more decompositions exist.
