Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047020, here are decompositions:

43 + 1046977 = 1047020
61 + 1046959 = 1047020
103 + 1046917 = 1047020
157 + 1046863 = 1047020
193 + 1046827 = 1047020
223 + 1046797 = 1047020
229 + 1046791 = 1047020
241 + 1046779 = 1047020

Showing the first eight; more decompositions exist.
