Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961542, here are decompositions:

11 + 961531 = 961542
13 + 961529 = 961542
31 + 961511 = 961542
83 + 961459 = 961542
89 + 961453 = 961542
149 + 961393 = 961542
223 + 961319 = 961542
229 + 961313 = 961542

Showing the first eight; more decompositions exist.
