Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991496, here are decompositions:

3 + 991493 = 991496
13 + 991483 = 991496
43 + 991453 = 991496
67 + 991429 = 991496
109 + 991387 = 991496
139 + 991357 = 991496
223 + 991273 = 991496
349 + 991147 = 991496

Showing the first eight; more decompositions exist.
