Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001644, here are decompositions:

5 + 1001639 = 1001644
23 + 1001621 = 1001644
113 + 1001531 = 1001644
197 + 1001447 = 1001644
233 + 1001411 = 1001644
257 + 1001387 = 1001644
263 + 1001381 = 1001644
317 + 1001327 = 1001644

Showing the first eight; more decompositions exist.
