Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051556, here are decompositions:

3 + 1051553 = 1051556
7 + 1051549 = 1051556
13 + 1051543 = 1051556
97 + 1051459 = 1051556
139 + 1051417 = 1051556
223 + 1051333 = 1051556
379 + 1051177 = 1051556
409 + 1051147 = 1051556

Showing the first eight; more decompositions exist.
