Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78188, here are decompositions:

31 + 78157 = 78188
67 + 78121 = 78188
109 + 78079 = 78188
139 + 78049 = 78188
157 + 78031 = 78188
181 + 78007 = 78188
211 + 77977 = 78188
349 + 77839 = 78188

Showing the first eight; more decompositions exist.
