Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961978, here are decompositions:

5 + 961973 = 961978
41 + 961937 = 961978
107 + 961871 = 961978
131 + 961847 = 961978
137 + 961841 = 961978
167 + 961811 = 961978
239 + 961739 = 961978
317 + 961661 = 961978

Showing the first eight; more decompositions exist.
