Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 587128, here are decompositions:

5 + 587123 = 587128
11 + 587117 = 587128
41 + 587087 = 587128
71 + 587057 = 587128
107 + 587021 = 587128
149 + 586979 = 587128
167 + 586961 = 587128
257 + 586871 = 587128

Showing the first eight; more decompositions exist.
