Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84078, here are decompositions:

11 + 84067 = 84078
17 + 84061 = 84078
19 + 84059 = 84078
31 + 84047 = 84078
61 + 84017 = 84078
67 + 84011 = 84078
109 + 83969 = 84078
139 + 83939 = 84078

Showing the first eight; more decompositions exist.
