Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005518, here are decompositions:

37 + 1005481 = 1005518
61 + 1005457 = 1005518
79 + 1005439 = 1005518
109 + 1005409 = 1005518
127 + 1005391 = 1005518
277 + 1005241 = 1005518
331 + 1005187 = 1005518
439 + 1005079 = 1005518

Showing the first eight; more decompositions exist.
