Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487500, here are decompositions:

11 + 487489 = 487500
19 + 487481 = 487500
23 + 487477 = 487500
29 + 487471 = 487500
31 + 487469 = 487500
37 + 487463 = 487500
43 + 487457 = 487500
53 + 487447 = 487500

Showing the first eight; more decompositions exist.
