Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618562, here are decompositions:

5 + 8618557 = 8618562
61 + 8618501 = 8618562
79 + 8618483 = 8618562
83 + 8618479 = 8618562
149 + 8618413 = 8618562
223 + 8618339 = 8618562
233 + 8618329 = 8618562
269 + 8618293 = 8618562

Showing the first eight; more decompositions exist.
