Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643474, here are decompositions:

17 + 8643457 = 8643474
31 + 8643443 = 8643474
41 + 8643433 = 8643474
107 + 8643367 = 8643474
131 + 8643343 = 8643474
137 + 8643337 = 8643474
157 + 8643317 = 8643474
167 + 8643307 = 8643474

Showing the first eight; more decompositions exist.
