Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020988, here are decompositions:

11 + 1020977 = 1020988
29 + 1020959 = 1020988
107 + 1020881 = 1020988
149 + 1020839 = 1020988
167 + 1020821 = 1020988
191 + 1020797 = 1020988
281 + 1020707 = 1020988
389 + 1020599 = 1020988

Showing the first eight; more decompositions exist.
