Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991454, here are decompositions:

7 + 991447 = 991454
67 + 991387 = 991454
73 + 991381 = 991454
97 + 991357 = 991454
127 + 991327 = 991454
181 + 991273 = 991454
193 + 991261 = 991454
283 + 991171 = 991454

Showing the first eight; more decompositions exist.
