Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945090, here are decompositions:

31 + 945059 = 945090
53 + 945037 = 945090
59 + 945031 = 945090
103 + 944987 = 945090
127 + 944963 = 945090
137 + 944953 = 945090
191 + 944899 = 945090
193 + 944897 = 945090

Showing the first eight; more decompositions exist.
