Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8020, here are decompositions:

3 + 8017 = 8020
11 + 8009 = 8020
71 + 7949 = 8020
83 + 7937 = 8020
101 + 7919 = 8020
113 + 7907 = 8020
137 + 7883 = 8020
167 + 7853 = 8020

Showing the first eight; more decompositions exist.
