Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055578, here are decompositions:

11 + 1055567 = 1055578
47 + 1055531 = 1055578
89 + 1055489 = 1055578
107 + 1055471 = 1055578
149 + 1055429 = 1055578
179 + 1055399 = 1055578
191 + 1055387 = 1055578
257 + 1055321 = 1055578

Showing the first eight; more decompositions exist.
