Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688038, here are decompositions:

109 + 8687929 = 8688038
127 + 8687911 = 8688038
157 + 8687881 = 8688038
211 + 8687827 = 8688038
241 + 8687797 = 8688038
367 + 8687671 = 8688038
379 + 8687659 = 8688038
397 + 8687641 = 8688038

Showing the first eight; more decompositions exist.
