Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487724, here are decompositions:

7 + 487717 = 487724
43 + 487681 = 487724
67 + 487657 = 487724
73 + 487651 = 487724
163 + 487561 = 487724
277 + 487447 = 487724
337 + 487387 = 487724
421 + 487303 = 487724

Showing the first eight; more decompositions exist.
