Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997426, here are decompositions:

47 + 997379 = 997426
83 + 997343 = 997426
107 + 997319 = 997426
167 + 997259 = 997426
179 + 997247 = 997426
263 + 997163 = 997426
317 + 997109 = 997426
383 + 997043 = 997426

Showing the first eight; more decompositions exist.
