Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961880, here are decompositions:

19 + 961861 = 961880
67 + 961813 = 961880
97 + 961783 = 961880
103 + 961777 = 961880
151 + 961729 = 961880
193 + 961687 = 961880
223 + 961657 = 961880
313 + 961567 = 961880

Showing the first eight; more decompositions exist.
