Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487980, here are decompositions:

7 + 487973 = 487980
37 + 487943 = 487980
47 + 487933 = 487980
83 + 487897 = 487980
89 + 487891 = 487980
107 + 487873 = 487980
137 + 487843 = 487980
149 + 487831 = 487980

Showing the first eight; more decompositions exist.
