Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658358, here are decompositions:

29 + 8658329 = 8658358
197 + 8658161 = 8658358
251 + 8658107 = 8658358
257 + 8658101 = 8658358
389 + 8657969 = 8658358
431 + 8657927 = 8658358
509 + 8657849 = 8658358
557 + 8657801 = 8658358

Showing the first eight; more decompositions exist.
