Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997826, here are decompositions:

13 + 997813 = 997826
19 + 997807 = 997826
43 + 997783 = 997826
127 + 997699 = 997826
163 + 997663 = 997826
199 + 997627 = 997826
229 + 997597 = 997826
373 + 997453 = 997826

Showing the first eight; more decompositions exist.
