Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487756, here are decompositions:

23 + 487733 = 487756
29 + 487727 = 487756
47 + 487709 = 487756
53 + 487703 = 487756
107 + 487649 = 487756
149 + 487607 = 487756
167 + 487589 = 487756
293 + 487463 = 487756

Showing the first eight; more decompositions exist.
