Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961642, here are decompositions:

5 + 961637 = 961642
23 + 961619 = 961642
29 + 961613 = 961642
41 + 961601 = 961642
113 + 961529 = 961642
131 + 961511 = 961642
191 + 961451 = 961642
359 + 961283 = 961642

Showing the first eight; more decompositions exist.
