Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756388, here are decompositions:

7 + 8756381 = 8756388
31 + 8756357 = 8756388
71 + 8756317 = 8756388
89 + 8756299 = 8756388
149 + 8756239 = 8756388
167 + 8756221 = 8756388
229 + 8756159 = 8756388
239 + 8756149 = 8756388

Showing the first eight; more decompositions exist.
