Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618588, here are decompositions:

7 + 8618581 = 8618588
31 + 8618557 = 8618588
109 + 8618479 = 8618588
211 + 8618377 = 8618588
271 + 8618317 = 8618588
331 + 8618257 = 8618588
337 + 8618251 = 8618588
367 + 8618221 = 8618588

Showing the first eight; more decompositions exist.
