Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015644, here are decompositions:

17 + 1015627 = 1015644
41 + 1015603 = 1015644
43 + 1015601 = 1015644
73 + 1015571 = 1015644
83 + 1015561 = 1015644
103 + 1015541 = 1015644
127 + 1015517 = 1015644
137 + 1015507 = 1015644

Showing the first eight; more decompositions exist.
