Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172182, here are decompositions:

11 + 172171 = 172182
13 + 172169 = 172182
29 + 172153 = 172182
89 + 172093 = 172182
103 + 172079 = 172182
113 + 172069 = 172182
151 + 172031 = 172182
173 + 172009 = 172182

Showing the first eight; more decompositions exist.
