Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171242, here are decompositions:

73 + 171169 = 171242
79 + 171163 = 171242
139 + 171103 = 171242
151 + 171091 = 171242
163 + 171079 = 171242
193 + 171049 = 171242
199 + 171043 = 171242
271 + 170971 = 171242

Showing the first eight; more decompositions exist.
