Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78158, here are decompositions:

19 + 78139 = 78158
37 + 78121 = 78158
79 + 78079 = 78158
109 + 78049 = 78158
127 + 78031 = 78158
151 + 78007 = 78158
181 + 77977 = 78158
229 + 77929 = 78158

Showing the first eight; more decompositions exist.
