Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045558, here are decompositions:

11 + 1045547 = 1045558
29 + 1045529 = 1045558
71 + 1045487 = 1045558
89 + 1045469 = 1045558
131 + 1045427 = 1045558
149 + 1045409 = 1045558
167 + 1045391 = 1045558
191 + 1045367 = 1045558

Showing the first eight; more decompositions exist.
