Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991466, here are decompositions:

13 + 991453 = 991466
19 + 991447 = 991466
37 + 991429 = 991466
79 + 991387 = 991466
109 + 991357 = 991466
139 + 991327 = 991466
193 + 991273 = 991466
337 + 991129 = 991466

Showing the first eight; more decompositions exist.
