Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688998, here are decompositions:

7 + 8688991 = 8688998
37 + 8688961 = 8688998
79 + 8688919 = 8688998
181 + 8688817 = 8688998
211 + 8688787 = 8688998
397 + 8688601 = 8688998
421 + 8688577 = 8688998
601 + 8688397 = 8688998

Showing the first eight; more decompositions exist.
