Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4020, here are decompositions:

7 + 4013 = 4020
13 + 4007 = 4020
17 + 4003 = 4020
19 + 4001 = 4020
31 + 3989 = 4020
53 + 3967 = 4020
73 + 3947 = 4020
89 + 3931 = 4020

Showing the first eight; more decompositions exist.
