Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651172, here are decompositions:

11 + 8651161 = 8651172
29 + 8651143 = 8651172
31 + 8651141 = 8651172
53 + 8651119 = 8651172
109 + 8651063 = 8651172
163 + 8651009 = 8651172
191 + 8650981 = 8651172
193 + 8650979 = 8651172

Showing the first eight; more decompositions exist.
