Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997898, here are decompositions:

7 + 997891 = 997898
19 + 997879 = 997898
157 + 997741 = 997898
199 + 997699 = 997898
271 + 997627 = 997898
541 + 997357 = 997898
571 + 997327 = 997898
619 + 997279 = 997898

Showing the first eight; more decompositions exist.
