Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051644, here are decompositions:

5 + 1051639 = 1051644
23 + 1051621 = 1051644
37 + 1051607 = 1051644
43 + 1051601 = 1051644
53 + 1051591 = 1051644
73 + 1051571 = 1051644
101 + 1051543 = 1051644
137 + 1051507 = 1051644

Showing the first eight; more decompositions exist.
