Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991546, here are decompositions:

5 + 991541 = 991546
47 + 991499 = 991546
53 + 991493 = 991546
137 + 991409 = 991546
233 + 991313 = 991546
317 + 991229 = 991546
359 + 991187 = 991546
419 + 991127 = 991546

Showing the first eight; more decompositions exist.
