Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997864, here are decompositions:

53 + 997811 = 997864
71 + 997793 = 997864
113 + 997751 = 997864
137 + 997727 = 997864
227 + 997637 = 997864
281 + 997583 = 997864
311 + 997553 = 997864
317 + 997547 = 997864

Showing the first eight; more decompositions exist.
