Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011572, here are decompositions:

13 + 1011559 = 1011572
19 + 1011553 = 1011572
181 + 1011391 = 1011572
223 + 1011349 = 1011572
229 + 1011343 = 1011572
241 + 1011331 = 1011572
283 + 1011289 = 1011572
409 + 1011163 = 1011572

Showing the first eight; more decompositions exist.
