Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012572, here are decompositions:

13 + 1012559 = 1012572
23 + 1012549 = 1012572
53 + 1012519 = 1012572
59 + 1012513 = 1012572
83 + 1012489 = 1012572
109 + 1012463 = 1012572
139 + 1012433 = 1012572
149 + 1012423 = 1012572

Showing the first eight; more decompositions exist.
