Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961988, here are decompositions:

7 + 961981 = 961988
31 + 961957 = 961988
61 + 961927 = 961988
109 + 961879 = 961988
127 + 961861 = 961988
199 + 961789 = 961988
211 + 961777 = 961988
241 + 961747 = 961988

Showing the first eight; more decompositions exist.
