Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045572, here are decompositions:

13 + 1045559 = 1045572
23 + 1045549 = 1045572
29 + 1045543 = 1045572
43 + 1045529 = 1045572
79 + 1045493 = 1045572
103 + 1045469 = 1045572
149 + 1045423 = 1045572
163 + 1045409 = 1045572

Showing the first eight; more decompositions exist.
