Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487528, here are decompositions:

47 + 487481 = 487528
59 + 487469 = 487528
71 + 487457 = 487528
101 + 487427 = 487528
131 + 487397 = 487528
137 + 487391 = 487528
179 + 487349 = 487528
281 + 487247 = 487528

Showing the first eight; more decompositions exist.
