Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487446, here are decompositions:

17 + 487429 = 487446
19 + 487427 = 487446
23 + 487423 = 487446
59 + 487387 = 487446
83 + 487363 = 487446
97 + 487349 = 487446
139 + 487307 = 487446
163 + 487283 = 487446

Showing the first eight; more decompositions exist.
