Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687698, here are decompositions:

11 + 8687687 = 8687698
29 + 8687669 = 8687698
269 + 8687429 = 8687698
311 + 8687387 = 8687698
317 + 8687381 = 8687698
389 + 8687309 = 8687698
449 + 8687249 = 8687698
491 + 8687207 = 8687698

Showing the first eight; more decompositions exist.
