Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991414, here are decompositions:

5 + 991409 = 991414
71 + 991343 = 991414
101 + 991313 = 991414
191 + 991223 = 991414
197 + 991217 = 991414
227 + 991187 = 991414
233 + 991181 = 991414
383 + 991031 = 991414

Showing the first eight; more decompositions exist.
