Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028804, here are decompositions:

31 + 1028773 = 1028804
43 + 1028761 = 1028804
67 + 1028737 = 1028804
157 + 1028647 = 1028804
223 + 1028581 = 1028804
331 + 1028473 = 1028804
367 + 1028437 = 1028804
487 + 1028317 = 1028804

Showing the first eight; more decompositions exist.
