Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997838, here are decompositions:

31 + 997807 = 997838
97 + 997741 = 997838
139 + 997699 = 997838
157 + 997681 = 997838
211 + 997627 = 997838
229 + 997609 = 997838
241 + 997597 = 997838
571 + 997267 = 997838

Showing the first eight; more decompositions exist.
