Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028810, here are decompositions:

7 + 1028803 = 1028810
37 + 1028773 = 1028810
61 + 1028749 = 1028810
73 + 1028737 = 1028810
127 + 1028683 = 1028810
163 + 1028647 = 1028810
193 + 1028617 = 1028810
229 + 1028581 = 1028810

Showing the first eight; more decompositions exist.
