Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487964, here are decompositions:

31 + 487933 = 487964
67 + 487897 = 487964
73 + 487891 = 487964
181 + 487783 = 487964
223 + 487741 = 487964
283 + 487681 = 487964
307 + 487657 = 487964
313 + 487651 = 487964

Showing the first eight; more decompositions exist.
