Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487498, here are decompositions:

17 + 487481 = 487498
29 + 487469 = 487498
41 + 487457 = 487498
71 + 487427 = 487498
101 + 487397 = 487498
107 + 487391 = 487498
149 + 487349 = 487498
191 + 487307 = 487498

Showing the first eight; more decompositions exist.
