Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487454, here are decompositions:

7 + 487447 = 487454
31 + 487423 = 487454
67 + 487387 = 487454
73 + 487381 = 487454
151 + 487303 = 487454
193 + 487261 = 487454
241 + 487213 = 487454
271 + 487183 = 487454

Showing the first eight; more decompositions exist.
