Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689868, here are decompositions:

139 + 8689729 = 8689868
157 + 8689711 = 8689868
181 + 8689687 = 8689868
211 + 8689657 = 8689868
241 + 8689627 = 8689868
277 + 8689591 = 8689868
331 + 8689537 = 8689868
379 + 8689489 = 8689868

Showing the first eight; more decompositions exist.
