Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048558, here are decompositions:

41 + 1048517 = 1048558
167 + 1048391 = 1048558
191 + 1048367 = 1048558
197 + 1048361 = 1048558
419 + 1048139 = 1048558
431 + 1048127 = 1048558
509 + 1048049 = 1048558
569 + 1047989 = 1048558

Showing the first eight; more decompositions exist.
