Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659238, here are decompositions:

19 + 8659219 = 8659238
31 + 8659207 = 8659238
139 + 8659099 = 8659238
229 + 8659009 = 8659238
241 + 8658997 = 8659238
277 + 8658961 = 8659238
307 + 8658931 = 8659238
409 + 8658829 = 8659238

Showing the first eight; more decompositions exist.
