Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487908, here are decompositions:

11 + 487897 = 487908
17 + 487891 = 487908
19 + 487889 = 487908
79 + 487829 = 487908
89 + 487819 = 487908
97 + 487811 = 487908
139 + 487769 = 487908
151 + 487757 = 487908

Showing the first eight; more decompositions exist.
