Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77850, here are decompositions:

11 + 77839 = 77850
37 + 77813 = 77850
53 + 77797 = 77850
67 + 77783 = 77850
89 + 77761 = 77850
103 + 77747 = 77850
107 + 77743 = 77850
127 + 77723 = 77850

Showing the first eight; more decompositions exist.
