Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003540, here are decompositions:

23 + 1003517 = 1003540
71 + 1003469 = 1003540
107 + 1003433 = 1003540
173 + 1003367 = 1003540
179 + 1003361 = 1003540
191 + 1003349 = 1003540
233 + 1003307 = 1003540
281 + 1003259 = 1003540

Showing the first eight; more decompositions exist.
