Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487040, here are decompositions:

19 + 487021 = 487040
97 + 486943 = 487040
223 + 486817 = 487040
271 + 486769 = 487040
283 + 486757 = 487040
373 + 486667 = 487040
397 + 486643 = 487040
439 + 486601 = 487040

Showing the first eight; more decompositions exist.
