Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042018, here are decompositions:

17 + 1042001 = 1042018
149 + 1041869 = 1042018
239 + 1041779 = 1042018
281 + 1041737 = 1042018
317 + 1041701 = 1042018
347 + 1041671 = 1042018
401 + 1041617 = 1042018
521 + 1041497 = 1042018

Showing the first eight; more decompositions exist.
