Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656072, here are decompositions:

3 + 8656069 = 8656072
41 + 8656031 = 8656072
53 + 8656019 = 8656072
149 + 8655923 = 8656072
263 + 8655809 = 8656072
311 + 8655761 = 8656072
353 + 8655719 = 8656072
401 + 8655671 = 8656072

Showing the first eight; more decompositions exist.
