Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77930, here are decompositions:

31 + 77899 = 77930
37 + 77893 = 77930
67 + 77863 = 77930
157 + 77773 = 77930
199 + 77731 = 77930
211 + 77719 = 77930
241 + 77689 = 77930
271 + 77659 = 77930

Showing the first eight; more decompositions exist.
