Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485490, here are decompositions:

11 + 485479 = 485490
43 + 485447 = 485490
53 + 485437 = 485490
67 + 485423 = 485490
73 + 485417 = 485490
79 + 485411 = 485490
101 + 485389 = 485490
107 + 485383 = 485490

Showing the first eight; more decompositions exist.
