Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047530, here are decompositions:

19 + 1047511 = 1047530
31 + 1047499 = 1047530
61 + 1047469 = 1047530
139 + 1047391 = 1047530
151 + 1047379 = 1047530
157 + 1047373 = 1047530
163 + 1047367 = 1047530
223 + 1047307 = 1047530

Showing the first eight; more decompositions exist.
