Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989018, here are decompositions:

7 + 989011 = 989018
67 + 988951 = 989018
109 + 988909 = 989018
157 + 988861 = 989018
181 + 988837 = 989018
229 + 988789 = 989018
307 + 988711 = 989018
337 + 988681 = 989018

Showing the first eight; more decompositions exist.
