Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487682, here are decompositions:

31 + 487651 = 487682
79 + 487603 = 487682
193 + 487489 = 487682
211 + 487471 = 487682
379 + 487303 = 487682
421 + 487261 = 487682
463 + 487219 = 487682
499 + 487183 = 487682

Showing the first eight; more decompositions exist.
