Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487518, here are decompositions:

11 + 487507 = 487518
29 + 487489 = 487518
37 + 487481 = 487518
41 + 487477 = 487518
47 + 487471 = 487518
61 + 487457 = 487518
71 + 487447 = 487518
89 + 487429 = 487518

Showing the first eight; more decompositions exist.
