Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78020, here are decompositions:

3 + 78017 = 78020
13 + 78007 = 78020
37 + 77983 = 78020
43 + 77977 = 78020
127 + 77893 = 78020
157 + 77863 = 78020
181 + 77839 = 78020
223 + 77797 = 78020

Showing the first eight; more decompositions exist.
