Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487512, here are decompositions:

5 + 487507 = 487512
23 + 487489 = 487512
31 + 487481 = 487512
41 + 487471 = 487512
43 + 487469 = 487512
83 + 487429 = 487512
89 + 487423 = 487512
131 + 487381 = 487512

Showing the first eight; more decompositions exist.
