Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945450, here are decompositions:

19 + 945431 = 945450
41 + 945409 = 945450
53 + 945397 = 945450
59 + 945391 = 945450
61 + 945389 = 945450
73 + 945377 = 945450
83 + 945367 = 945450
101 + 945349 = 945450

Showing the first eight; more decompositions exist.
