Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623888, here are decompositions:

5 + 8623883 = 8623888
41 + 8623847 = 8623888
89 + 8623799 = 8623888
101 + 8623787 = 8623888
131 + 8623757 = 8623888
137 + 8623751 = 8623888
167 + 8623721 = 8623888
227 + 8623661 = 8623888

Showing the first eight; more decompositions exist.
