Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627172, here are decompositions:

5 + 8627167 = 8627172
11 + 8627161 = 8627172
19 + 8627153 = 8627172
23 + 8627149 = 8627172
31 + 8627141 = 8627172
53 + 8627119 = 8627172
61 + 8627111 = 8627172
139 + 8627033 = 8627172

Showing the first eight; more decompositions exist.
