Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997874, here are decompositions:

61 + 997813 = 997874
67 + 997807 = 997874
181 + 997693 = 997874
193 + 997681 = 997874
211 + 997663 = 997874
223 + 997651 = 997874
277 + 997597 = 997874
421 + 997453 = 997874

Showing the first eight; more decompositions exist.
