Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042858, here are decompositions:

29 + 1042829 = 1042858
59 + 1042799 = 1042858
149 + 1042709 = 1042858
227 + 1042631 = 1042858
239 + 1042619 = 1042858
251 + 1042607 = 1042858
281 + 1042577 = 1042858
389 + 1042469 = 1042858

Showing the first eight; more decompositions exist.
