Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991596, here are decompositions:

17 + 991579 = 991596
29 + 991567 = 991596
97 + 991499 = 991596
103 + 991493 = 991596
113 + 991483 = 991596
149 + 991447 = 991596
167 + 991429 = 991596
239 + 991357 = 991596

Showing the first eight; more decompositions exist.
