Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003646, here are decompositions:

19 + 1003627 = 1003646
37 + 1003609 = 1003646
97 + 1003549 = 1003646
103 + 1003543 = 1003646
139 + 1003507 = 1003646
229 + 1003417 = 1003646
277 + 1003369 = 1003646
283 + 1003363 = 1003646

Showing the first eight; more decompositions exist.
