Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487946, here are decompositions:

3 + 487943 = 487946
13 + 487933 = 487946
73 + 487873 = 487946
103 + 487843 = 487946
127 + 487819 = 487946
157 + 487789 = 487946
163 + 487783 = 487946
229 + 487717 = 487946

Showing the first eight; more decompositions exist.
