Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187082, here are decompositions:

13 + 187069 = 187082
73 + 187009 = 187082
79 + 187003 = 187082
193 + 186889 = 187082
199 + 186883 = 187082
211 + 186871 = 187082
223 + 186859 = 187082
241 + 186841 = 187082

Showing the first eight; more decompositions exist.
