Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655172, here are decompositions:

5 + 8655167 = 8655172
23 + 8655149 = 8655172
101 + 8655071 = 8655172
131 + 8655041 = 8655172
191 + 8654981 = 8655172
401 + 8654771 = 8655172
419 + 8654753 = 8655172
443 + 8654729 = 8655172

Showing the first eight; more decompositions exist.
