Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945420, here are decompositions:

11 + 945409 = 945420
23 + 945397 = 945420
29 + 945391 = 945420
31 + 945389 = 945420
43 + 945377 = 945420
53 + 945367 = 945420
61 + 945359 = 945420
71 + 945349 = 945420

Showing the first eight; more decompositions exist.
