Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605742, here are decompositions:

181 + 8605561 = 8605742
199 + 8605543 = 8605742
241 + 8605501 = 8605742
331 + 8605411 = 8605742
373 + 8605369 = 8605742
571 + 8605171 = 8605742
751 + 8604991 = 8605742
829 + 8604913 = 8605742

Showing the first eight; more decompositions exist.
