Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77966, here are decompositions:

37 + 77929 = 77966
67 + 77899 = 77966
73 + 77893 = 77966
103 + 77863 = 77966
127 + 77839 = 77966
193 + 77773 = 77966
223 + 77743 = 77966
277 + 77689 = 77966

Showing the first eight; more decompositions exist.
