Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487404, here are decompositions:

7 + 487397 = 487404
13 + 487391 = 487404
17 + 487387 = 487404
23 + 487381 = 487404
41 + 487363 = 487404
97 + 487307 = 487404
101 + 487303 = 487404
157 + 487247 = 487404

Showing the first eight; more decompositions exist.
