Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961998, here are decompositions:

5 + 961993 = 961998
7 + 961991 = 961998
17 + 961981 = 961998
41 + 961957 = 961998
61 + 961937 = 961998
71 + 961927 = 961998
127 + 961871 = 961998
137 + 961861 = 961998

Showing the first eight; more decompositions exist.
