Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91722, here are decompositions:

11 + 91711 = 91722
19 + 91703 = 91722
31 + 91691 = 91722
83 + 91639 = 91722
101 + 91621 = 91722
131 + 91591 = 91722
139 + 91583 = 91722
149 + 91573 = 91722

Showing the first eight; more decompositions exist.
