Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997398, here are decompositions:

7 + 997391 = 997398
19 + 997379 = 997398
29 + 997369 = 997398
41 + 997357 = 997398
71 + 997327 = 997398
79 + 997319 = 997398
89 + 997309 = 997398
131 + 997267 = 997398

Showing the first eight; more decompositions exist.
