Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486428, here are decompositions:

31 + 486397 = 486428
37 + 486391 = 486428
79 + 486349 = 486428
97 + 486331 = 486428
181 + 486247 = 486428
337 + 486091 = 486428
367 + 486061 = 486428
487 + 485941 = 486428

Showing the first eight; more decompositions exist.
