Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172112, here are decompositions:

19 + 172093 = 172112
43 + 172069 = 172112
103 + 172009 = 172112
223 + 171889 = 172112
313 + 171799 = 172112
349 + 171763 = 172112
379 + 171733 = 172112
433 + 171679 = 172112

Showing the first eight; more decompositions exist.
