Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487508, here are decompositions:

19 + 487489 = 487508
31 + 487477 = 487508
37 + 487471 = 487508
61 + 487447 = 487508
79 + 487429 = 487508
127 + 487381 = 487508
331 + 487177 = 487508
397 + 487111 = 487508

Showing the first eight; more decompositions exist.
