Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003644, here are decompositions:

13 + 1003631 = 1003644
17 + 1003627 = 1003644
23 + 1003621 = 1003644
43 + 1003601 = 1003644
101 + 1003543 = 1003644
127 + 1003517 = 1003644
137 + 1003507 = 1003644
181 + 1003463 = 1003644

Showing the first eight; more decompositions exist.
