Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487340, here are decompositions:

37 + 487303 = 487340
79 + 487261 = 487340
127 + 487213 = 487340
157 + 487183 = 487340
163 + 487177 = 487340
229 + 487111 = 487340
241 + 487099 = 487340
283 + 487057 = 487340

Showing the first eight; more decompositions exist.
