Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656162, here are decompositions:

3 + 8656159 = 8656162
29 + 8656133 = 8656162
71 + 8656091 = 8656162
83 + 8656079 = 8656162
131 + 8656031 = 8656162
239 + 8655923 = 8656162
293 + 8655869 = 8656162
353 + 8655809 = 8656162

Showing the first eight; more decompositions exist.
