Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998018, here are decompositions:

127 + 997891 = 998018
139 + 997879 = 998018
211 + 997807 = 998018
277 + 997741 = 998018
337 + 997681 = 998018
367 + 997651 = 998018
409 + 997609 = 998018
421 + 997597 = 998018

Showing the first eight; more decompositions exist.
