Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656426, here are decompositions:

3 + 8656423 = 8656426
47 + 8656379 = 8656426
59 + 8656367 = 8656426
113 + 8656313 = 8656426
173 + 8656253 = 8656426
257 + 8656169 = 8656426
263 + 8656163 = 8656426
293 + 8656133 = 8656426

Showing the first eight; more decompositions exist.
