Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66778, here are decompositions:

29 + 66749 = 66778
149 + 66629 = 66778
191 + 66587 = 66778
269 + 66509 = 66778
311 + 66467 = 66778
347 + 66431 = 66778
401 + 66377 = 66778
419 + 66359 = 66778

Showing the first eight; more decompositions exist.
