Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997842, here are decompositions:

29 + 997813 = 997842
31 + 997811 = 997842
59 + 997783 = 997842
73 + 997769 = 997842
101 + 997741 = 997842
103 + 997739 = 997842
149 + 997693 = 997842
179 + 997663 = 997842

Showing the first eight; more decompositions exist.
