Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991494, here are decompositions:

11 + 991483 = 991494
41 + 991453 = 991494
47 + 991447 = 991494
67 + 991427 = 991494
107 + 991387 = 991494
113 + 991381 = 991494
137 + 991357 = 991494
151 + 991343 = 991494

Showing the first eight; more decompositions exist.
