Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997902, here are decompositions:

5 + 997897 = 997902
11 + 997891 = 997902
13 + 997889 = 997902
23 + 997879 = 997902
89 + 997813 = 997902
109 + 997793 = 997902
151 + 997751 = 997902
163 + 997739 = 997902

Showing the first eight; more decompositions exist.
