Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005560, here are decompositions:

7 + 1005553 = 1005560
19 + 1005541 = 1005560
67 + 1005493 = 1005560
79 + 1005481 = 1005560
103 + 1005457 = 1005560
151 + 1005409 = 1005560
211 + 1005349 = 1005560
229 + 1005331 = 1005560

Showing the first eight; more decompositions exist.
