Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658328, here are decompositions:

5 + 8658323 = 8658328
167 + 8658161 = 8658328
191 + 8658137 = 8658328
227 + 8658101 = 8658328
269 + 8658059 = 8658328
311 + 8658017 = 8658328
359 + 8657969 = 8658328
401 + 8657927 = 8658328

Showing the first eight; more decompositions exist.
