Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007540, here are decompositions:

13 + 1007527 = 1007540
43 + 1007497 = 1007540
73 + 1007467 = 1007540
139 + 1007401 = 1007540
181 + 1007359 = 1007540
223 + 1007317 = 1007540
241 + 1007299 = 1007540
337 + 1007203 = 1007540

Showing the first eight; more decompositions exist.
