Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045406, here are decompositions:

13 + 1045393 = 1045406
97 + 1045309 = 1045406
223 + 1045183 = 1045406
277 + 1045129 = 1045406
283 + 1045123 = 1045406
379 + 1045027 = 1045406
409 + 1044997 = 1045406
547 + 1044859 = 1045406

Showing the first eight; more decompositions exist.
