Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43020, here are decompositions:

7 + 43013 = 43020
17 + 43003 = 43020
31 + 42989 = 43020
41 + 42979 = 43020
53 + 42967 = 43020
59 + 42961 = 43020
67 + 42953 = 43020
83 + 42937 = 43020

Showing the first eight; more decompositions exist.
