Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618492, here are decompositions:

13 + 8618479 = 8618492
79 + 8618413 = 8618492
163 + 8618329 = 8618492
199 + 8618293 = 8618492
241 + 8618251 = 8618492
271 + 8618221 = 8618492
373 + 8618119 = 8618492
409 + 8618083 = 8618492

Showing the first eight; more decompositions exist.
