Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85020, here are decompositions:

11 + 85009 = 85020
29 + 84991 = 85020
41 + 84979 = 85020
43 + 84977 = 85020
53 + 84967 = 85020
59 + 84961 = 85020
73 + 84947 = 85020
101 + 84919 = 85020

Showing the first eight; more decompositions exist.
