Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008644, here are decompositions:

31 + 1008613 = 1008644
37 + 1008607 = 1008644
73 + 1008571 = 1008644
97 + 1008547 = 1008644
103 + 1008541 = 1008644
127 + 1008517 = 1008644
151 + 1008493 = 1008644
193 + 1008451 = 1008644

Showing the first eight; more decompositions exist.
