Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77938, here are decompositions:

5 + 77933 = 77938
71 + 77867 = 77938
89 + 77849 = 77938
137 + 77801 = 77938
191 + 77747 = 77938
227 + 77711 = 77938
239 + 77699 = 77938
251 + 77687 = 77938

Showing the first eight; more decompositions exist.
