Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605018, here are decompositions:

17 + 8605001 = 8605018
41 + 8604977 = 8605018
239 + 8604779 = 8605018
251 + 8604767 = 8605018
269 + 8604749 = 8605018
311 + 8604707 = 8605018
467 + 8604551 = 8605018
479 + 8604539 = 8605018

Showing the first eight; more decompositions exist.
