Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003640, here are decompositions:

13 + 1003627 = 1003640
19 + 1003621 = 1003640
31 + 1003609 = 1003640
97 + 1003543 = 1003640
223 + 1003417 = 1003640
229 + 1003411 = 1003640
271 + 1003369 = 1003640
277 + 1003363 = 1003640

Showing the first eight; more decompositions exist.
