Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78150, here are decompositions:

11 + 78139 = 78150
13 + 78137 = 78150
29 + 78121 = 78150
71 + 78079 = 78150
101 + 78049 = 78150
109 + 78041 = 78150
151 + 77999 = 78150
167 + 77983 = 78150

Showing the first eight; more decompositions exist.
