Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487904, here are decompositions:

7 + 487897 = 487904
13 + 487891 = 487904
31 + 487873 = 487904
61 + 487843 = 487904
73 + 487831 = 487904
163 + 487741 = 487904
223 + 487681 = 487904
397 + 487507 = 487904

Showing the first eight; more decompositions exist.
