Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997858, here are decompositions:

47 + 997811 = 997858
89 + 997769 = 997858
107 + 997751 = 997858
131 + 997727 = 997858
269 + 997589 = 997858
311 + 997547 = 997858
317 + 997541 = 997858
347 + 997511 = 997858

Showing the first eight; more decompositions exist.
