Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609398, here are decompositions:

89 + 8609309 = 8609398
101 + 8609297 = 8609398
191 + 8609207 = 8609398
269 + 8609129 = 8609398
311 + 8609087 = 8609398
467 + 8608931 = 8609398
491 + 8608907 = 8609398
509 + 8608889 = 8609398

Showing the first eight; more decompositions exist.
