Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656146, here are decompositions:

13 + 8656133 = 8656146
17 + 8656129 = 8656146
29 + 8656117 = 8656146
53 + 8656093 = 8656146
67 + 8656079 = 8656146
89 + 8656057 = 8656146
113 + 8656033 = 8656146
127 + 8656019 = 8656146

Showing the first eight; more decompositions exist.
