Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945000, here are decompositions:

13 + 944987 = 945000
31 + 944969 = 945000
37 + 944963 = 945000
47 + 944953 = 945000
71 + 944929 = 945000
101 + 944899 = 945000
103 + 944897 = 945000
107 + 944893 = 945000

Showing the first eight; more decompositions exist.
