Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944540, here are decompositions:

7 + 944533 = 944540
13 + 944527 = 944540
19 + 944521 = 944540
43 + 944497 = 944540
67 + 944473 = 944540
73 + 944467 = 944540
109 + 944431 = 944540
151 + 944389 = 944540

Showing the first eight; more decompositions exist.
