Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78164, here are decompositions:

7 + 78157 = 78164
43 + 78121 = 78164
157 + 78007 = 78164
181 + 77983 = 78164
271 + 77893 = 78164
367 + 77797 = 78164
421 + 77743 = 78164
433 + 77731 = 78164

Showing the first eight; more decompositions exist.
