Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689888, here are decompositions:

47 + 8689841 = 8689888
71 + 8689817 = 8689888
89 + 8689799 = 8689888
227 + 8689661 = 8689888
239 + 8689649 = 8689888
359 + 8689529 = 8689888
569 + 8689319 = 8689888
587 + 8689301 = 8689888

Showing the first eight; more decompositions exist.
