Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003578, here are decompositions:

29 + 1003549 = 1003578
61 + 1003517 = 1003578
71 + 1003507 = 1003578
109 + 1003469 = 1003578
167 + 1003411 = 1003578
181 + 1003397 = 1003578
197 + 1003381 = 1003578
211 + 1003367 = 1003578

Showing the first eight; more decompositions exist.
