Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617868, here are decompositions:

31 + 8617837 = 8617868
241 + 8617627 = 8617868
307 + 8617561 = 8617868
349 + 8617519 = 8617868
421 + 8617447 = 8617868
487 + 8617381 = 8617868
541 + 8617327 = 8617868
577 + 8617291 = 8617868

Showing the first eight; more decompositions exist.
