Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66776, here are decompositions:

13 + 66763 = 66776
37 + 66739 = 66776
43 + 66733 = 66776
79 + 66697 = 66776
223 + 66553 = 66776
277 + 66499 = 66776
313 + 66463 = 66776
373 + 66403 = 66776

Showing the first eight; more decompositions exist.
