Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997824, here are decompositions:

11 + 997813 = 997824
13 + 997811 = 997824
17 + 997807 = 997824
31 + 997793 = 997824
41 + 997783 = 997824
73 + 997751 = 997824
83 + 997741 = 997824
97 + 997727 = 997824

Showing the first eight; more decompositions exist.
