Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597172, here are decompositions:

13 + 8597159 = 8597172
29 + 8597143 = 8597172
61 + 8597111 = 8597172
79 + 8597093 = 8597172
113 + 8597059 = 8597172
131 + 8597041 = 8597172
149 + 8597023 = 8597172
191 + 8596981 = 8597172

Showing the first eight; more decompositions exist.
