Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487944, here are decompositions:

11 + 487933 = 487944
47 + 487897 = 487944
53 + 487891 = 487944
71 + 487873 = 487944
101 + 487843 = 487944
113 + 487831 = 487944
151 + 487793 = 487944
211 + 487733 = 487944

Showing the first eight; more decompositions exist.
