Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78180, here are decompositions:

7 + 78173 = 78180
13 + 78167 = 78180
17 + 78163 = 78180
23 + 78157 = 78180
41 + 78139 = 78180
43 + 78137 = 78180
59 + 78121 = 78180
79 + 78101 = 78180

Showing the first eight; more decompositions exist.
