Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487556, here are decompositions:

67 + 487489 = 487556
79 + 487477 = 487556
109 + 487447 = 487556
127 + 487429 = 487556
193 + 487363 = 487556
337 + 487219 = 487556
373 + 487183 = 487556
379 + 487177 = 487556

Showing the first eight; more decompositions exist.
