Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42020, here are decompositions:

3 + 42017 = 42020
7 + 42013 = 42020
37 + 41983 = 42020
61 + 41959 = 42020
67 + 41953 = 42020
73 + 41947 = 42020
79 + 41941 = 42020
109 + 41911 = 42020

Showing the first eight; more decompositions exist.
