Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172198, here are decompositions:

17 + 172181 = 172198
29 + 172169 = 172198
41 + 172157 = 172198
71 + 172127 = 172198
101 + 172097 = 172198
149 + 172049 = 172198
167 + 172031 = 172198
197 + 172001 = 172198

Showing the first eight; more decompositions exist.
