Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997810, here are decompositions:

3 + 997807 = 997810
17 + 997793 = 997810
41 + 997769 = 997810
59 + 997751 = 997810
71 + 997739 = 997810
83 + 997727 = 997810
173 + 997637 = 997810
227 + 997583 = 997810

Showing the first eight; more decompositions exist.
