Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487502, here are decompositions:

13 + 487489 = 487502
31 + 487471 = 487502
73 + 487429 = 487502
79 + 487423 = 487502
139 + 487363 = 487502
199 + 487303 = 487502
241 + 487261 = 487502
283 + 487219 = 487502

Showing the first eight; more decompositions exist.
