Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 936842, here are decompositions:

31 + 936811 = 936842
73 + 936769 = 936842
103 + 936739 = 936842
163 + 936679 = 936842
223 + 936619 = 936842
331 + 936511 = 936842
349 + 936493 = 936842
373 + 936469 = 936842

Showing the first eight; more decompositions exist.
