Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77950, here are decompositions:

17 + 77933 = 77950
83 + 77867 = 77950
101 + 77849 = 77950
137 + 77813 = 77950
149 + 77801 = 77950
167 + 77783 = 77950
227 + 77723 = 77950
239 + 77711 = 77950

Showing the first eight; more decompositions exist.
