Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961438, here are decompositions:

11 + 961427 = 961438
41 + 961397 = 961438
197 + 961241 = 961438
251 + 961187 = 961438
281 + 961157 = 961438
347 + 961091 = 961438
449 + 960989 = 961438
461 + 960977 = 961438

Showing the first eight; more decompositions exist.
