Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487428, here are decompositions:

5 + 487423 = 487428
31 + 487397 = 487428
37 + 487391 = 487428
41 + 487387 = 487428
47 + 487381 = 487428
79 + 487349 = 487428
167 + 487261 = 487428
181 + 487247 = 487428

Showing the first eight; more decompositions exist.
