Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997744, here are decompositions:

3 + 997741 = 997744
5 + 997739 = 997744
17 + 997727 = 997744
107 + 997637 = 997744
191 + 997553 = 997744
197 + 997547 = 997744
233 + 997511 = 997744
281 + 997463 = 997744

Showing the first eight; more decompositions exist.
