Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669860, here are decompositions:

29 + 8669831 = 8669860
83 + 8669777 = 8669860
191 + 8669669 = 8669860
233 + 8669627 = 8669860
239 + 8669621 = 8669860
317 + 8669543 = 8669860
347 + 8669513 = 8669860
359 + 8669501 = 8669860

Showing the first eight; more decompositions exist.
