Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172118, here are decompositions:

97 + 172021 = 172118
109 + 172009 = 172118
181 + 171937 = 172118
229 + 171889 = 172118
241 + 171877 = 172118
307 + 171811 = 172118
421 + 171697 = 172118
439 + 171679 = 172118

Showing the first eight; more decompositions exist.
