Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997862, here are decompositions:

79 + 997783 = 997862
163 + 997699 = 997862
181 + 997681 = 997862
199 + 997663 = 997862
211 + 997651 = 997862
409 + 997453 = 997862
643 + 997219 = 997862
661 + 997201 = 997862

Showing the first eight; more decompositions exist.
