Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667898, here are decompositions:

89 + 8667809 = 8667898
101 + 8667797 = 8667898
191 + 8667707 = 8667898
257 + 8667641 = 8667898
359 + 8667539 = 8667898
401 + 8667497 = 8667898
467 + 8667431 = 8667898
479 + 8667419 = 8667898

Showing the first eight; more decompositions exist.
