Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942838, here are decompositions:

11 + 942827 = 942838
59 + 942779 = 942838
89 + 942749 = 942838
179 + 942659 = 942838
269 + 942569 = 942838
311 + 942527 = 942838
317 + 942521 = 942838
359 + 942479 = 942838

Showing the first eight; more decompositions exist.
