Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487526, here are decompositions:

19 + 487507 = 487526
37 + 487489 = 487526
79 + 487447 = 487526
97 + 487429 = 487526
103 + 487423 = 487526
139 + 487387 = 487526
163 + 487363 = 487526
223 + 487303 = 487526

Showing the first eight; more decompositions exist.
