Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945540, here are decompositions:

19 + 945521 = 945540
59 + 945481 = 945540
61 + 945479 = 945540
67 + 945473 = 945540
83 + 945457 = 945540
109 + 945431 = 945540
131 + 945409 = 945540
149 + 945391 = 945540

Showing the first eight; more decompositions exist.
