Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997802, here are decompositions:

19 + 997783 = 997802
61 + 997741 = 997802
103 + 997699 = 997802
109 + 997693 = 997802
139 + 997663 = 997802
151 + 997651 = 997802
193 + 997609 = 997802
229 + 997573 = 997802

Showing the first eight; more decompositions exist.
