Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972172, here are decompositions:

11 + 972161 = 972172
41 + 972131 = 972172
53 + 972119 = 972172
59 + 972113 = 972172
101 + 972071 = 972172
191 + 971981 = 972172
233 + 971939 = 972172
239 + 971933 = 972172

Showing the first eight; more decompositions exist.
