Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99172, here are decompositions:

23 + 99149 = 99172
41 + 99131 = 99172
53 + 99119 = 99172
83 + 99089 = 99172
89 + 99083 = 99172
131 + 99041 = 99172
149 + 99023 = 99172
173 + 98999 = 99172

Showing the first eight; more decompositions exist.
