Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647474, here are decompositions:

5 + 8647469 = 8647474
83 + 8647391 = 8647474
107 + 8647367 = 8647474
197 + 8647277 = 8647474
281 + 8647193 = 8647474
293 + 8647181 = 8647474
317 + 8647157 = 8647474
347 + 8647127 = 8647474

Showing the first eight; more decompositions exist.
