Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008572, here are decompositions:

31 + 1008541 = 1008572
73 + 1008499 = 1008572
79 + 1008493 = 1008572
139 + 1008433 = 1008572
151 + 1008421 = 1008572
163 + 1008409 = 1008572
193 + 1008379 = 1008572
199 + 1008373 = 1008572

Showing the first eight; more decompositions exist.
