Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78084, here are decompositions:

5 + 78079 = 78084
43 + 78041 = 78084
53 + 78031 = 78084
67 + 78017 = 78084
101 + 77983 = 78084
107 + 77977 = 78084
151 + 77933 = 78084
191 + 77893 = 78084

Showing the first eight; more decompositions exist.
