Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940686, here are decompositions:

17 + 940669 = 940686
37 + 940649 = 940686
67 + 940619 = 940686
79 + 940607 = 940686
113 + 940573 = 940686
137 + 940549 = 940686
139 + 940547 = 940686
157 + 940529 = 940686

Showing the first eight; more decompositions exist.
