Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616172, here are decompositions:

3 + 8616169 = 8616172
23 + 8616149 = 8616172
41 + 8616131 = 8616172
83 + 8616089 = 8616172
101 + 8616071 = 8616172
281 + 8615891 = 8616172
293 + 8615879 = 8616172
401 + 8615771 = 8616172

Showing the first eight; more decompositions exist.
