Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688818, here are decompositions:

31 + 8688787 = 8688818
79 + 8688739 = 8688818
211 + 8688607 = 8688818
241 + 8688577 = 8688818
349 + 8688469 = 8688818
409 + 8688409 = 8688818
421 + 8688397 = 8688818
547 + 8688271 = 8688818

Showing the first eight; more decompositions exist.
