Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623258, here are decompositions:

5 + 8623253 = 8623258
11 + 8623247 = 8623258
191 + 8623067 = 8623258
197 + 8623061 = 8623258
227 + 8623031 = 8623258
239 + 8623019 = 8623258
401 + 8622857 = 8623258
491 + 8622767 = 8623258

Showing the first eight; more decompositions exist.
