Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126020, here are decompositions:

7 + 126013 = 126020
19 + 126001 = 126020
61 + 125959 = 126020
79 + 125941 = 126020
157 + 125863 = 126020
199 + 125821 = 126020
229 + 125791 = 126020
277 + 125743 = 126020

Showing the first eight; more decompositions exist.
