Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658178, here are decompositions:

17 + 8658161 = 8658178
41 + 8658137 = 8658178
71 + 8658107 = 8658178
251 + 8657927 = 8658178
479 + 8657699 = 8658178
491 + 8657687 = 8658178
797 + 8657381 = 8658178
821 + 8657357 = 8658178

Showing the first eight; more decompositions exist.
