Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64020, here are decompositions:

7 + 64013 = 64020
13 + 64007 = 64020
23 + 63997 = 64020
43 + 63977 = 64020
71 + 63949 = 64020
107 + 63913 = 64020
113 + 63907 = 64020
157 + 63863 = 64020

Showing the first eight; more decompositions exist.
