Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663388, here are decompositions:

31 + 8663357 = 8663388
79 + 8663309 = 8663388
109 + 8663279 = 8663388
127 + 8663261 = 8663388
179 + 8663209 = 8663388
269 + 8663119 = 8663388
271 + 8663117 = 8663388
317 + 8663071 = 8663388

Showing the first eight; more decompositions exist.
