Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057158, here are decompositions:

29 + 1057129 = 1057158
41 + 1057117 = 1057158
71 + 1057087 = 1057158
107 + 1057051 = 1057158
139 + 1057019 = 1057158
199 + 1056959 = 1057158
229 + 1056929 = 1057158
241 + 1056917 = 1057158

Showing the first eight; more decompositions exist.
