Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055490, here are decompositions:

19 + 1055471 = 1055490
53 + 1055437 = 1055490
61 + 1055429 = 1055490
67 + 1055423 = 1055490
83 + 1055407 = 1055490
103 + 1055387 = 1055490
127 + 1055363 = 1055490
131 + 1055359 = 1055490

Showing the first eight; more decompositions exist.
