Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656258, here are decompositions:

5 + 8656253 = 8656258
89 + 8656169 = 8656258
167 + 8656091 = 8656258
179 + 8656079 = 8656258
227 + 8656031 = 8656258
239 + 8656019 = 8656258
389 + 8655869 = 8656258
449 + 8655809 = 8656258

Showing the first eight; more decompositions exist.
