Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77928, here are decompositions:

29 + 77899 = 77928
61 + 77867 = 77928
79 + 77849 = 77928
89 + 77839 = 77928
127 + 77801 = 77928
131 + 77797 = 77928
167 + 77761 = 77928
181 + 77747 = 77928

Showing the first eight; more decompositions exist.
