Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172194, here are decompositions:

13 + 172181 = 172194
23 + 172171 = 172194
37 + 172157 = 172194
41 + 172153 = 172194
47 + 172147 = 172194
67 + 172127 = 172194
97 + 172097 = 172194
101 + 172093 = 172194

Showing the first eight; more decompositions exist.
