Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997078, here are decompositions:

41 + 997037 = 997078
59 + 997019 = 997078
179 + 996899 = 997078
191 + 996887 = 997078
197 + 996881 = 997078
389 + 996689 = 997078
431 + 996647 = 997078
449 + 996629 = 997078

Showing the first eight; more decompositions exist.
