Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991926, here are decompositions:

17 + 991909 = 991926
37 + 991889 = 991926
43 + 991883 = 991926
53 + 991873 = 991926
59 + 991867 = 991926
109 + 991817 = 991926
149 + 991777 = 991926
193 + 991733 = 991926

Showing the first eight; more decompositions exist.
