Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997726, here are decompositions:

89 + 997637 = 997726
137 + 997589 = 997726
173 + 997553 = 997726
179 + 997547 = 997726
263 + 997463 = 997726
293 + 997433 = 997726
347 + 997379 = 997726
383 + 997343 = 997726

Showing the first eight; more decompositions exist.
