Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961918, here are decompositions:

47 + 961871 = 961918
71 + 961847 = 961918
101 + 961817 = 961918
107 + 961811 = 961918
149 + 961769 = 961918
179 + 961739 = 961918
227 + 961691 = 961918
239 + 961679 = 961918

Showing the first eight; more decompositions exist.
