Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045644, here are decompositions:

11 + 1045633 = 1045644
23 + 1045621 = 1045644
37 + 1045607 = 1045644
71 + 1045573 = 1045644
73 + 1045571 = 1045644
97 + 1045547 = 1045644
101 + 1045543 = 1045644
137 + 1045507 = 1045644

Showing the first eight; more decompositions exist.
