Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656402, here are decompositions:

3 + 8656399 = 8656402
23 + 8656379 = 8656402
89 + 8656313 = 8656402
149 + 8656253 = 8656402
233 + 8656169 = 8656402
239 + 8656163 = 8656402
269 + 8656133 = 8656402
311 + 8656091 = 8656402

Showing the first eight; more decompositions exist.
