Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991676, here are decompositions:

13 + 991663 = 991676
43 + 991633 = 991676
73 + 991603 = 991676
97 + 991579 = 991676
109 + 991567 = 991676
193 + 991483 = 991676
223 + 991453 = 991676
229 + 991447 = 991676

Showing the first eight; more decompositions exist.
