Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985572, here are decompositions:

41 + 985531 = 985572
43 + 985529 = 985572
53 + 985519 = 985572
73 + 985499 = 985572
79 + 985493 = 985572
89 + 985483 = 985572
101 + 985471 = 985572
109 + 985463 = 985572

Showing the first eight; more decompositions exist.
