Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78146, here are decompositions:

7 + 78139 = 78146
67 + 78079 = 78146
97 + 78049 = 78146
139 + 78007 = 78146
163 + 77983 = 78146
283 + 77863 = 78146
307 + 77839 = 78146
349 + 77797 = 78146

Showing the first eight; more decompositions exist.
