Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989090, here are decompositions:

19 + 989071 = 989090
31 + 989059 = 989090
61 + 989029 = 989090
79 + 989011 = 989090
127 + 988963 = 989090
139 + 988951 = 989090
181 + 988909 = 989090
229 + 988861 = 989090

Showing the first eight; more decompositions exist.
