Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670398, here are decompositions:

67 + 8670331 = 8670398
97 + 8670301 = 8670398
241 + 8670157 = 8670398
271 + 8670127 = 8670398
367 + 8670031 = 8670398
409 + 8669989 = 8670398
487 + 8669911 = 8670398
577 + 8669821 = 8670398

Showing the first eight; more decompositions exist.
