Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66790, here are decompositions:

41 + 66749 = 66790
89 + 66701 = 66790
107 + 66683 = 66790
137 + 66653 = 66790
173 + 66617 = 66790
197 + 66593 = 66790
257 + 66533 = 66790
281 + 66509 = 66790

Showing the first eight; more decompositions exist.
