Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000988, here are decompositions:

7 + 1000981 = 1000988
19 + 1000969 = 1000988
67 + 1000921 = 1000988
127 + 1000861 = 1000988
139 + 1000849 = 1000988
211 + 1000777 = 1000988
337 + 1000651 = 1000988
349 + 1000639 = 1000988

Showing the first eight; more decompositions exist.
