Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66772, here are decompositions:

23 + 66749 = 66772
59 + 66713 = 66772
71 + 66701 = 66772
89 + 66683 = 66772
179 + 66593 = 66772
239 + 66533 = 66772
263 + 66509 = 66772
281 + 66491 = 66772

Showing the first eight; more decompositions exist.
