Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992390, here are decompositions:

19 + 992371 = 992390
31 + 992359 = 992390
73 + 992317 = 992390
109 + 992281 = 992390
127 + 992263 = 992390
211 + 992179 = 992390
277 + 992113 = 992390
367 + 992023 = 992390

Showing the first eight; more decompositions exist.
