Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989020, here are decompositions:

41 + 988979 = 989020
83 + 988937 = 989020
191 + 988829 = 989020
257 + 988763 = 989020
293 + 988727 = 989020
359 + 988661 = 989020
443 + 988577 = 989020
449 + 988571 = 989020

Showing the first eight; more decompositions exist.
