Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999080, here are decompositions:

13 + 999067 = 999080
31 + 999049 = 999080
37 + 999043 = 999080
73 + 999007 = 999080
97 + 998983 = 999080
139 + 998941 = 999080
163 + 998917 = 999080
223 + 998857 = 999080

Showing the first eight; more decompositions exist.
