Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618396, here are decompositions:

19 + 8618377 = 8618396
67 + 8618329 = 8618396
79 + 8618317 = 8618396
103 + 8618293 = 8618396
109 + 8618287 = 8618396
139 + 8618257 = 8618396
223 + 8618173 = 8618396
277 + 8618119 = 8618396

Showing the first eight; more decompositions exist.
