Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025572, here are decompositions:

11 + 1025561 = 1025572
29 + 1025543 = 1025572
59 + 1025513 = 1025572
89 + 1025483 = 1025572
113 + 1025459 = 1025572
179 + 1025393 = 1025572
239 + 1025333 = 1025572
269 + 1025303 = 1025572

Showing the first eight; more decompositions exist.
