Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005572, here are decompositions:

19 + 1005553 = 1005572
31 + 1005541 = 1005572
79 + 1005493 = 1005572
163 + 1005409 = 1005572
181 + 1005391 = 1005572
199 + 1005373 = 1005572
223 + 1005349 = 1005572
241 + 1005331 = 1005572

Showing the first eight; more decompositions exist.
