Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003558, here are decompositions:

41 + 1003517 = 1003558
89 + 1003469 = 1003558
191 + 1003367 = 1003558
197 + 1003361 = 1003558
251 + 1003307 = 1003558
317 + 1003241 = 1003558
359 + 1003199 = 1003558
449 + 1003109 = 1003558

Showing the first eight; more decompositions exist.
