Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656312, here are decompositions:

29 + 8656283 = 8656312
59 + 8656253 = 8656312
149 + 8656163 = 8656312
179 + 8656133 = 8656312
233 + 8656079 = 8656312
281 + 8656031 = 8656312
293 + 8656019 = 8656312
359 + 8655953 = 8656312

Showing the first eight; more decompositions exist.
