Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487516, here are decompositions:

47 + 487469 = 487516
53 + 487463 = 487516
59 + 487457 = 487516
89 + 487427 = 487516
167 + 487349 = 487516
233 + 487283 = 487516
269 + 487247 = 487516
383 + 487133 = 487516

Showing the first eight; more decompositions exist.
