Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940780, here are decompositions:

41 + 940739 = 940780
47 + 940733 = 940780
53 + 940727 = 940780
59 + 940721 = 940780
89 + 940691 = 940780
131 + 940649 = 940780
173 + 940607 = 940780
227 + 940553 = 940780

Showing the first eight; more decompositions exist.
