Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003858, here are decompositions:

17 + 1003841 = 1003858
41 + 1003817 = 1003858
71 + 1003787 = 1003858
101 + 1003757 = 1003858
179 + 1003679 = 1003858
227 + 1003631 = 1003858
239 + 1003619 = 1003858
257 + 1003601 = 1003858

Showing the first eight; more decompositions exist.
