Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961428, here are decompositions:

29 + 961399 = 961428
31 + 961397 = 961428
89 + 961339 = 961428
109 + 961319 = 961428
151 + 961277 = 961428
227 + 961201 = 961428
239 + 961189 = 961428
241 + 961187 = 961428

Showing the first eight; more decompositions exist.
