Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055566, here are decompositions:

23 + 1055543 = 1055566
137 + 1055429 = 1055566
167 + 1055399 = 1055566
179 + 1055387 = 1055566
263 + 1055303 = 1055566
503 + 1055063 = 1055566
509 + 1055057 = 1055566
797 + 1054769 = 1055566

Showing the first eight; more decompositions exist.
