Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487664, here are decompositions:

7 + 487657 = 487664
13 + 487651 = 487664
61 + 487603 = 487664
103 + 487561 = 487664
157 + 487507 = 487664
193 + 487471 = 487664
241 + 487423 = 487664
277 + 487387 = 487664

Showing the first eight; more decompositions exist.
