Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055556, here are decompositions:

13 + 1055543 = 1055556
53 + 1055503 = 1055556
67 + 1055489 = 1055556
127 + 1055429 = 1055556
149 + 1055407 = 1055556
157 + 1055399 = 1055556
193 + 1055363 = 1055556
197 + 1055359 = 1055556

Showing the first eight; more decompositions exist.
