Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657340, here are decompositions:

7 + 8657333 = 8657340
17 + 8657323 = 8657340
31 + 8657309 = 8657340
101 + 8657239 = 8657340
103 + 8657237 = 8657340
179 + 8657161 = 8657340
229 + 8657111 = 8657340
271 + 8657069 = 8657340

Showing the first eight; more decompositions exist.
