Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171146, here are decompositions:

43 + 171103 = 171146
67 + 171079 = 171146
97 + 171049 = 171146
103 + 171043 = 171146
139 + 171007 = 171146
193 + 170953 = 171146
337 + 170809 = 171146
373 + 170773 = 171146

Showing the first eight; more decompositions exist.
