Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051858, here are decompositions:

11 + 1051847 = 1051858
29 + 1051829 = 1051858
47 + 1051811 = 1051858
149 + 1051709 = 1051858
239 + 1051619 = 1051858
251 + 1051607 = 1051858
257 + 1051601 = 1051858
359 + 1051499 = 1051858

Showing the first eight; more decompositions exist.
