Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617558, here are decompositions:

11 + 8617547 = 8617558
167 + 8617391 = 8617558
197 + 8617361 = 8617558
239 + 8617319 = 8617558
281 + 8617277 = 8617558
347 + 8617211 = 8617558
449 + 8617109 = 8617558
461 + 8617097 = 8617558

Showing the first eight; more decompositions exist.
