Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611398, here are decompositions:

17 + 8611381 = 8611398
41 + 8611357 = 8611398
67 + 8611331 = 8611398
97 + 8611301 = 8611398
101 + 8611297 = 8611398
137 + 8611261 = 8611398
149 + 8611249 = 8611398
151 + 8611247 = 8611398

Showing the first eight; more decompositions exist.
