Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997854, here are decompositions:

41 + 997813 = 997854
43 + 997811 = 997854
47 + 997807 = 997854
61 + 997793 = 997854
71 + 997783 = 997854
103 + 997751 = 997854
113 + 997741 = 997854
127 + 997727 = 997854

Showing the first eight; more decompositions exist.
