Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997830, here are decompositions:

17 + 997813 = 997830
19 + 997811 = 997830
23 + 997807 = 997830
37 + 997793 = 997830
47 + 997783 = 997830
61 + 997769 = 997830
79 + 997751 = 997830
89 + 997741 = 997830

Showing the first eight; more decompositions exist.
