Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485128, here are decompositions:

5 + 485123 = 485128
47 + 485081 = 485128
107 + 485021 = 485128
359 + 484769 = 485128
401 + 484727 = 485128
521 + 484607 = 485128
641 + 484487 = 485128
827 + 484301 = 485128

Showing the first eight; more decompositions exist.
