Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991434, here are decompositions:

5 + 991429 = 991434
7 + 991427 = 991434
47 + 991387 = 991434
53 + 991381 = 991434
107 + 991327 = 991434
173 + 991261 = 991434
211 + 991223 = 991434
233 + 991201 = 991434

Showing the first eight; more decompositions exist.
