Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487656, here are decompositions:

5 + 487651 = 487656
7 + 487649 = 487656
19 + 487637 = 487656
53 + 487603 = 487656
67 + 487589 = 487656
149 + 487507 = 487656
167 + 487489 = 487656
179 + 487477 = 487656

Showing the first eight; more decompositions exist.
