Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011556, here are decompositions:

3 + 1011553 = 1011556
17 + 1011539 = 1011556
47 + 1011509 = 1011556
113 + 1011443 = 1011556
149 + 1011407 = 1011556
179 + 1011377 = 1011556
197 + 1011359 = 1011556
317 + 1011239 = 1011556

Showing the first eight; more decompositions exist.
