Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78006, here are decompositions:

7 + 77999 = 78006
23 + 77983 = 78006
29 + 77977 = 78006
37 + 77969 = 78006
73 + 77933 = 78006
107 + 77899 = 78006
113 + 77893 = 78006
139 + 77867 = 78006

Showing the first eight; more decompositions exist.
