Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997894, here are decompositions:

3 + 997891 = 997894
5 + 997889 = 997894
17 + 997877 = 997894
83 + 997811 = 997894
101 + 997793 = 997894
167 + 997727 = 997894
257 + 997637 = 997894
311 + 997583 = 997894

Showing the first eight; more decompositions exist.
