Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487884, here are decompositions:

11 + 487873 = 487884
41 + 487843 = 487884
53 + 487831 = 487884
73 + 487811 = 487884
101 + 487783 = 487884
127 + 487757 = 487884
151 + 487733 = 487884
157 + 487727 = 487884

Showing the first eight; more decompositions exist.
