Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688988, here are decompositions:

179 + 8688809 = 8688988
197 + 8688791 = 8688988
281 + 8688707 = 8688988
317 + 8688671 = 8688988
359 + 8688629 = 8688988
419 + 8688569 = 8688988
431 + 8688557 = 8688988
461 + 8688527 = 8688988

Showing the first eight; more decompositions exist.
