Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492020, here are decompositions:

3 + 492017 = 492020
7 + 492013 = 492020
13 + 492007 = 492020
37 + 491983 = 492020
43 + 491977 = 492020
97 + 491923 = 492020
163 + 491857 = 492020
223 + 491797 = 492020

Showing the first eight; more decompositions exist.
