Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487188, here are decompositions:

5 + 487183 = 487188
11 + 487177 = 487188
89 + 487099 = 487188
109 + 487079 = 487188
131 + 487057 = 487188
137 + 487051 = 487188
139 + 487049 = 487188
167 + 487021 = 487188

Showing the first eight; more decompositions exist.
