Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487718, here are decompositions:

37 + 487681 = 487718
61 + 487657 = 487718
67 + 487651 = 487718
157 + 487561 = 487718
211 + 487507 = 487718
229 + 487489 = 487718
241 + 487477 = 487718
271 + 487447 = 487718

Showing the first eight; more decompositions exist.
