Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487658, here are decompositions:

7 + 487651 = 487658
97 + 487561 = 487658
151 + 487507 = 487658
181 + 487477 = 487658
211 + 487447 = 487658
229 + 487429 = 487658
271 + 487387 = 487658
277 + 487381 = 487658

Showing the first eight; more decompositions exist.
