Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487858, here are decompositions:

29 + 487829 = 487858
47 + 487811 = 487858
89 + 487769 = 487858
101 + 487757 = 487858
131 + 487727 = 487858
149 + 487709 = 487858
167 + 487691 = 487858
251 + 487607 = 487858

Showing the first eight; more decompositions exist.
