Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997860, here are decompositions:

47 + 997813 = 997860
53 + 997807 = 997860
67 + 997793 = 997860
109 + 997751 = 997860
167 + 997693 = 997860
179 + 997681 = 997860
197 + 997663 = 997860
211 + 997649 = 997860

Showing the first eight; more decompositions exist.
