Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011728, here are decompositions:

31 + 1011697 = 1011728
61 + 1011667 = 1011728
79 + 1011649 = 1011728
97 + 1011631 = 1011728
127 + 1011601 = 1011728
139 + 1011589 = 1011728
331 + 1011397 = 1011728
337 + 1011391 = 1011728

Showing the first eight; more decompositions exist.
