Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997390, here are decompositions:

11 + 997379 = 997390
47 + 997343 = 997390
71 + 997319 = 997390
83 + 997307 = 997390
131 + 997259 = 997390
227 + 997163 = 997390
239 + 997151 = 997390
269 + 997121 = 997390

Showing the first eight; more decompositions exist.
