Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940720, here are decompositions:

17 + 940703 = 940720
29 + 940691 = 940720
71 + 940649 = 940720
101 + 940619 = 940720
113 + 940607 = 940720
167 + 940553 = 940720
173 + 940547 = 940720
191 + 940529 = 940720

Showing the first eight; more decompositions exist.
