Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008520, here are decompositions:

3 + 1008517 = 1008520
17 + 1008503 = 1008520
53 + 1008467 = 1008520
83 + 1008437 = 1008520
101 + 1008419 = 1008520
113 + 1008407 = 1008520
167 + 1008353 = 1008520
173 + 1008347 = 1008520

Showing the first eight; more decompositions exist.
