Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055530, here are decompositions:

29 + 1055501 = 1055530
41 + 1055489 = 1055530
59 + 1055471 = 1055530
101 + 1055429 = 1055530
107 + 1055423 = 1055530
131 + 1055399 = 1055530
167 + 1055363 = 1055530
227 + 1055303 = 1055530

Showing the first eight; more decompositions exist.
