Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024858, here are decompositions:

5 + 1024853 = 1024858
59 + 1024799 = 1024858
101 + 1024757 = 1024858
137 + 1024721 = 1024858
269 + 1024589 = 1024858
281 + 1024577 = 1024858
311 + 1024547 = 1024858
347 + 1024511 = 1024858

Showing the first eight; more decompositions exist.
