Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618918, here are decompositions:

67 + 8618851 = 8618918
109 + 8618809 = 8618918
181 + 8618737 = 8618918
229 + 8618689 = 8618918
337 + 8618581 = 8618918
439 + 8618479 = 8618918
541 + 8618377 = 8618918
601 + 8618317 = 8618918

Showing the first eight; more decompositions exist.
