Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487490, here are decompositions:

13 + 487477 = 487490
19 + 487471 = 487490
43 + 487447 = 487490
61 + 487429 = 487490
67 + 487423 = 487490
103 + 487387 = 487490
109 + 487381 = 487490
127 + 487363 = 487490

Showing the first eight; more decompositions exist.
