Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997912, here are decompositions:

23 + 997889 = 997912
101 + 997811 = 997912
173 + 997739 = 997912
263 + 997649 = 997912
359 + 997553 = 997912
401 + 997511 = 997912
449 + 997463 = 997912
479 + 997433 = 997912

Showing the first eight; more decompositions exist.
