Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997850, here are decompositions:

37 + 997813 = 997850
43 + 997807 = 997850
67 + 997783 = 997850
109 + 997741 = 997850
151 + 997699 = 997850
157 + 997693 = 997850
199 + 997651 = 997850
223 + 997627 = 997850

Showing the first eight; more decompositions exist.
