Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656156, here are decompositions:

23 + 8656133 = 8656156
59 + 8656097 = 8656156
137 + 8656019 = 8656156
233 + 8655923 = 8656156
239 + 8655917 = 8656156
347 + 8655809 = 8656156
449 + 8655707 = 8656156
479 + 8655677 = 8656156

Showing the first eight; more decompositions exist.
