Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487928, here are decompositions:

31 + 487897 = 487928
37 + 487891 = 487928
97 + 487831 = 487928
109 + 487819 = 487928
139 + 487789 = 487928
211 + 487717 = 487928
271 + 487657 = 487928
277 + 487651 = 487928

Showing the first eight; more decompositions exist.
