Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657358, here are decompositions:

67 + 8657291 = 8657358
109 + 8657249 = 8657358
137 + 8657221 = 8657358
197 + 8657161 = 8657358
317 + 8657041 = 8657358
337 + 8657021 = 8657358
349 + 8657009 = 8657358
379 + 8656979 = 8657358

Showing the first eight; more decompositions exist.
