Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042206, here are decompositions:

13 + 1042193 = 1042206
19 + 1042187 = 1042206
23 + 1042183 = 1042206
73 + 1042133 = 1042206
83 + 1042123 = 1042206
97 + 1042109 = 1042206
103 + 1042103 = 1042206
107 + 1042099 = 1042206

Showing the first eight; more decompositions exist.
