Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989040, here are decompositions:

11 + 989029 = 989040
29 + 989011 = 989040
61 + 988979 = 989040
89 + 988951 = 989040
103 + 988937 = 989040
131 + 988909 = 989040
139 + 988901 = 989040
163 + 988877 = 989040

Showing the first eight; more decompositions exist.
