Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055406, here are decompositions:

7 + 1055399 = 1055406
19 + 1055387 = 1055406
43 + 1055363 = 1055406
47 + 1055359 = 1055406
59 + 1055347 = 1055406
103 + 1055303 = 1055406
137 + 1055269 = 1055406
139 + 1055267 = 1055406

Showing the first eight; more decompositions exist.
