Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992478, here are decompositions:

17 + 992461 = 992478
29 + 992449 = 992478
37 + 992441 = 992478
41 + 992437 = 992478
61 + 992417 = 992478
107 + 992371 = 992478
197 + 992281 = 992478
211 + 992267 = 992478

Showing the first eight; more decompositions exist.
