Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487206, here are decompositions:

19 + 487187 = 487206
23 + 487183 = 487206
29 + 487177 = 487206
73 + 487133 = 487206
107 + 487099 = 487206
113 + 487093 = 487206
127 + 487079 = 487206
149 + 487057 = 487206

Showing the first eight; more decompositions exist.
