Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659172, here are decompositions:

19 + 8659153 = 8659172
73 + 8659099 = 8659172
163 + 8659009 = 8659172
211 + 8658961 = 8659172
229 + 8658943 = 8659172
241 + 8658931 = 8659172
433 + 8658739 = 8659172
463 + 8658709 = 8659172

Showing the first eight; more decompositions exist.
