Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78230, here are decompositions:

37 + 78193 = 78230
67 + 78163 = 78230
73 + 78157 = 78230
109 + 78121 = 78230
151 + 78079 = 78230
181 + 78049 = 78230
199 + 78031 = 78230
223 + 78007 = 78230

Showing the first eight; more decompositions exist.
