Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055442, here are decompositions:

5 + 1055437 = 1055442
13 + 1055429 = 1055442
19 + 1055423 = 1055442
29 + 1055413 = 1055442
43 + 1055399 = 1055442
71 + 1055371 = 1055442
79 + 1055363 = 1055442
83 + 1055359 = 1055442

Showing the first eight; more decompositions exist.
