Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618558, here are decompositions:

79 + 8618479 = 8618558
181 + 8618377 = 8618558
229 + 8618329 = 8618558
241 + 8618317 = 8618558
271 + 8618287 = 8618558
307 + 8618251 = 8618558
337 + 8618221 = 8618558
409 + 8618149 = 8618558

Showing the first eight; more decompositions exist.
