Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961618, here are decompositions:

5 + 961613 = 961618
17 + 961601 = 961618
71 + 961547 = 961618
89 + 961529 = 961618
107 + 961511 = 961618
131 + 961487 = 961618
167 + 961451 = 961618
191 + 961427 = 961618

Showing the first eight; more decompositions exist.
