Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997018, here are decompositions:

5 + 997013 = 997018
17 + 997001 = 997018
131 + 996887 = 997018
137 + 996881 = 997018
389 + 996629 = 997018
401 + 996617 = 997018
419 + 996599 = 997018
467 + 996551 = 997018

Showing the first eight; more decompositions exist.
