Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66786, here are decompositions:

23 + 66763 = 66786
37 + 66749 = 66786
47 + 66739 = 66786
53 + 66733 = 66786
73 + 66713 = 66786
89 + 66697 = 66786
103 + 66683 = 66786
157 + 66629 = 66786

Showing the first eight; more decompositions exist.
