Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90020, here are decompositions:

3 + 90017 = 90020
13 + 90007 = 90020
19 + 90001 = 90020
31 + 89989 = 90020
37 + 89983 = 90020
43 + 89977 = 90020
61 + 89959 = 90020
97 + 89923 = 90020

Showing the first eight; more decompositions exist.
