Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66842, here are decompositions:

79 + 66763 = 66842
103 + 66739 = 66842
109 + 66733 = 66842
199 + 66643 = 66842
241 + 66601 = 66842
271 + 66571 = 66842
313 + 66529 = 66842
379 + 66463 = 66842

Showing the first eight; more decompositions exist.
