Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91720, here are decompositions:

17 + 91703 = 91720
29 + 91691 = 91720
47 + 91673 = 91720
89 + 91631 = 91720
137 + 91583 = 91720
149 + 91571 = 91720
179 + 91541 = 91720
191 + 91529 = 91720

Showing the first eight; more decompositions exist.
