Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961878, here are decompositions:

7 + 961871 = 961878
17 + 961861 = 961878
31 + 961847 = 961878
37 + 961841 = 961878
61 + 961817 = 961878
67 + 961811 = 961878
89 + 961789 = 961878
101 + 961777 = 961878

Showing the first eight; more decompositions exist.
