Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042798, here are decompositions:

17 + 1042781 = 1042798
89 + 1042709 = 1042798
167 + 1042631 = 1042798
179 + 1042619 = 1042798
191 + 1042607 = 1042798
227 + 1042571 = 1042798
269 + 1042529 = 1042798
311 + 1042487 = 1042798

Showing the first eight; more decompositions exist.
