Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172082, here are decompositions:

3 + 172079 = 172082
13 + 172069 = 172082
61 + 172021 = 172082
73 + 172009 = 172082
193 + 171889 = 172082
271 + 171811 = 172082
283 + 171799 = 172082
349 + 171733 = 172082

Showing the first eight; more decompositions exist.
