Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044428, here are decompositions:

19 + 1044409 = 1044428
31 + 1044397 = 1044428
37 + 1044391 = 1044428
61 + 1044367 = 1044428
139 + 1044289 = 1044428
157 + 1044271 = 1044428
181 + 1044247 = 1044428
211 + 1044217 = 1044428

Showing the first eight; more decompositions exist.
