Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487906, here are decompositions:

17 + 487889 = 487906
113 + 487793 = 487906
137 + 487769 = 487906
149 + 487757 = 487906
173 + 487733 = 487906
179 + 487727 = 487906
197 + 487709 = 487906
257 + 487649 = 487906

Showing the first eight; more decompositions exist.
