Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003556, here are decompositions:

7 + 1003549 = 1003556
13 + 1003543 = 1003556
139 + 1003417 = 1003556
193 + 1003363 = 1003556
277 + 1003279 = 1003556
283 + 1003273 = 1003556
577 + 1002979 = 1003556
643 + 1002913 = 1003556

Showing the first eight; more decompositions exist.
