Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047018, here are decompositions:

19 + 1046999 = 1047018
41 + 1046977 = 1047018
59 + 1046959 = 1047018
67 + 1046951 = 1047018
101 + 1046917 = 1047018
151 + 1046867 = 1047018
191 + 1046827 = 1047018
211 + 1046807 = 1047018

Showing the first eight; more decompositions exist.
