Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940728, here are decompositions:

7 + 940721 = 940728
37 + 940691 = 940728
59 + 940669 = 940728
79 + 940649 = 940728
109 + 940619 = 940728
179 + 940549 = 940728
181 + 940547 = 940728
197 + 940531 = 940728

Showing the first eight; more decompositions exist.
