Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656120, here are decompositions:

3 + 8656117 = 8656120
23 + 8656097 = 8656120
29 + 8656091 = 8656120
41 + 8656079 = 8656120
89 + 8656031 = 8656120
101 + 8656019 = 8656120
167 + 8655953 = 8656120
197 + 8655923 = 8656120

Showing the first eight; more decompositions exist.
