Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613018, here are decompositions:

17 + 8613001 = 8613018
59 + 8612959 = 8613018
61 + 8612957 = 8613018
157 + 8612861 = 8613018
179 + 8612839 = 8613018
181 + 8612837 = 8613018
241 + 8612777 = 8613018
251 + 8612767 = 8613018

Showing the first eight; more decompositions exist.
