Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617898, here are decompositions:

61 + 8617837 = 8617898
199 + 8617699 = 8617898
271 + 8617627 = 8617898
337 + 8617561 = 8617898
349 + 8617549 = 8617898
379 + 8617519 = 8617898
571 + 8617327 = 8617898
607 + 8617291 = 8617898

Showing the first eight; more decompositions exist.
