Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991464, here are decompositions:

11 + 991453 = 991464
17 + 991447 = 991464
37 + 991427 = 991464
83 + 991381 = 991464
107 + 991357 = 991464
137 + 991327 = 991464
151 + 991313 = 991464
191 + 991273 = 991464

Showing the first eight; more decompositions exist.
