Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042486, here are decompositions:

17 + 1042469 = 1042486
47 + 1042439 = 1042486
59 + 1042427 = 1042486
113 + 1042373 = 1042486
227 + 1042259 = 1042486
293 + 1042193 = 1042486
353 + 1042133 = 1042486
383 + 1042103 = 1042486

Showing the first eight; more decompositions exist.
