Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487654, here are decompositions:

3 + 487651 = 487654
5 + 487649 = 487654
17 + 487637 = 487654
47 + 487607 = 487654
53 + 487601 = 487654
173 + 487481 = 487654
191 + 487463 = 487654
197 + 487457 = 487654

Showing the first eight; more decompositions exist.
