Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942020, here are decompositions:

3 + 942017 = 942020
7 + 942013 = 942020
31 + 941989 = 942020
73 + 941947 = 942020
109 + 941911 = 942020
181 + 941839 = 942020
229 + 941791 = 942020
283 + 941737 = 942020

Showing the first eight; more decompositions exist.
