Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637398, here are decompositions:

19 + 8637379 = 8637398
61 + 8637337 = 8637398
79 + 8637319 = 8637398
97 + 8637301 = 8637398
109 + 8637289 = 8637398
151 + 8637247 = 8637398
307 + 8637091 = 8637398
331 + 8637067 = 8637398

Showing the first eight; more decompositions exist.
