Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997090, here are decompositions:

47 + 997043 = 997090
53 + 997037 = 997090
71 + 997019 = 997090
89 + 997001 = 997090
137 + 996953 = 997090
191 + 996899 = 997090
233 + 996857 = 997090
401 + 996689 = 997090

Showing the first eight; more decompositions exist.
