Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003550, here are decompositions:

7 + 1003543 = 1003550
43 + 1003507 = 1003550
139 + 1003411 = 1003550
181 + 1003369 = 1003550
199 + 1003351 = 1003550
271 + 1003279 = 1003550
277 + 1003273 = 1003550
349 + 1003201 = 1003550

Showing the first eight; more decompositions exist.
