Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042406, here are decompositions:

7 + 1042399 = 1042406
37 + 1042369 = 1042406
73 + 1042333 = 1042406
97 + 1042309 = 1042406
139 + 1042267 = 1042406
163 + 1042243 = 1042406
223 + 1042183 = 1042406
283 + 1042123 = 1042406

Showing the first eight; more decompositions exist.
