Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487660, here are decompositions:

3 + 487657 = 487660
11 + 487649 = 487660
23 + 487637 = 487660
53 + 487607 = 487660
59 + 487601 = 487660
71 + 487589 = 487660
179 + 487481 = 487660
191 + 487469 = 487660

Showing the first eight; more decompositions exist.
