Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999040, here are decompositions:

11 + 999029 = 999040
17 + 999023 = 999040
71 + 998969 = 999040
83 + 998957 = 999040
89 + 998951 = 999040
113 + 998927 = 999040
131 + 998909 = 999040
179 + 998861 = 999040

Showing the first eight; more decompositions exist.
