Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998020, here are decompositions:

3 + 998017 = 998020
11 + 998009 = 998020
29 + 997991 = 998020
47 + 997973 = 998020
59 + 997961 = 998020
71 + 997949 = 998020
131 + 997889 = 998020
227 + 997793 = 998020

Showing the first eight; more decompositions exist.
