Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997042, here are decompositions:

5 + 997037 = 997042
23 + 997019 = 997042
29 + 997013 = 997042
41 + 997001 = 997042
89 + 996953 = 997042
239 + 996803 = 997042
353 + 996689 = 997042
443 + 996599 = 997042

Showing the first eight; more decompositions exist.
