Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66774, here are decompositions:

11 + 66763 = 66774
23 + 66751 = 66774
41 + 66733 = 66774
53 + 66721 = 66774
61 + 66713 = 66774
73 + 66701 = 66774
131 + 66643 = 66774
157 + 66617 = 66774

Showing the first eight; more decompositions exist.
