Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002572, here are decompositions:

3 + 1002569 = 1002572
19 + 1002553 = 1002572
61 + 1002511 = 1002572
79 + 1002493 = 1002572
139 + 1002433 = 1002572
211 + 1002361 = 1002572
223 + 1002349 = 1002572
229 + 1002343 = 1002572

Showing the first eight; more decompositions exist.
