Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716388, here are decompositions:

7 + 8716381 = 8716388
139 + 8716249 = 8716388
151 + 8716237 = 8716388
181 + 8716207 = 8716388
229 + 8716159 = 8716388
349 + 8716039 = 8716388
367 + 8716021 = 8716388
487 + 8715901 = 8716388

Showing the first eight; more decompositions exist.
