Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940828, here are decompositions:

11 + 940817 = 940828
41 + 940787 = 940828
47 + 940781 = 940828
89 + 940739 = 940828
101 + 940727 = 940828
107 + 940721 = 940828
137 + 940691 = 940828
179 + 940649 = 940828

Showing the first eight; more decompositions exist.
