Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988012, here are decompositions:

5 + 988007 = 988012
29 + 987983 = 988012
41 + 987971 = 988012
71 + 987941 = 988012
83 + 987929 = 988012
101 + 987911 = 988012
191 + 987821 = 988012
353 + 987659 = 988012

Showing the first eight; more decompositions exist.
